Ævar Arnfjörð Bjarmason d162b25f95 tests: remove support for GIT_TEST_GETTEXT_POISON
This removes the ability to inject "poison" gettext() messages via the
GIT_TEST_GETTEXT_POISON special test setup.

I initially added this as a compile-time option in bb946bba76 (i18n:
add GETTEXT_POISON to simulate unfriendly translator, 2011-02-22), and
most recently modified to be toggleable at runtime in
6cdccfce1e (i18n: make GETTEXT_POISON a runtime option, 2018-11-08)..

The reason for its removal is that the trade-off of maintaining it
v.s. what it's getting us has long since flipped. When gettext was
integrated in 5e9637c629 (i18n: add infrastructure for translating
Git with gettext, 2011-11-18) there was understandable concern on the
Git ML that in marking messages for translation en-masse we'd
inadvertently mark plumbing messages. The GETTEXT_POISON facility was
a way to smoke those out via our test suite.

Nowadays however we're done (or almost entirely done) with any marking
of messages for translation. New messages are usually marked by their
authors, who'll know whether it makes sense to translate them or
not. If not any errors in marking the messages are much more likely to
be spotted in review than in the the initial deluge of i18n patches in
the 2011-2012 era.

So let's just remove this. This leaves the test suite in a state where
we still have a lot of test_i18n, C_LOCALE_OUTPUT
etc. uses. Subsequent commits will remove those too.

The change to t/lib-rebase.sh is a selective revert of the relevant
part of f2d17068fd (i18n: rebase-interactive: mark comments of squash
for translation, 2016-06-17), and the comment in
t/t3406-rebase-message.sh is from c7108bf9ed (i18n: rebase: mark
messages for translation, 2012-07-25).

# Helper functions used by interactive rebase tests.
# After setting the fake editor with this function, you can
#
# - override the commit message with $FAKE_COMMIT_MESSAGE
# - amend the commit message with $FAKE_COMMIT_AMEND
# - check that non-commit messages have a certain line count with $EXPECT_COUNT
# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
# - rewrite a rebase -i script as directed by $FAKE_LINES.
# $FAKE_LINES consists of a sequence of words separated by spaces.
# The following word combinations are possible:
#
# "<lineno>" -- add a "pick" line with the SHA1 taken from the
# specified line.
#
# "<cmd> <lineno>" -- add a line with the specified command
# ("pick", "squash", "fixup", "edit", "reword" or "drop") and the
# SHA1 taken from the specified line.
#
# "exec_cmd_with_args" -- add an "exec cmd with args" line.
#
# "#" -- Add a comment line.
#
# ">" -- Add a blank line.
