Elias Naur 7523baed09 misc/ios,cmd/go, runtime/cgo: fix iOS test harness (again)
The iOS test harness was recently changed in response to lldb bugs
to replace breakpoints with the SIGUSR2 signal (CL 34926), and to
pass the current directory in the test binary arguments (CL 35152).
Both the signal sending and working directory setup is done from
the go test driver.

However, the new method doesn't work with tests where a C program is
the test driver instead of go test: the current working directory
will not be changed and SIGUSR2 is not raised.

Instead of copying that logic into any C test program, rework the
test harness (again) to move the setup logic to the early runtime
cgo setup code. That way, the harness will run even in the library
build modes.

Then, use the app Info.plist file to pass the working
directory, removing the need to alter the arguments after running.

Finally, use the SIGINT signal instead of SIGUSR2 to avoid
manipulating the signal masks or handlers.

Fixes the testcarchive tests on iOS.

With this CL, both darwin/arm and darwin/arm64 passes all.bash.

This CL replaces CL 34926, CL 35152 as well as the fixup CL
35123 and CL 35255. They are reverted in CLs earlier in the
relation chain.
