Stephen J. Kiernan fa08011a52 zoneinfo: fix makefile rules script
In make target rules, one needs to use subshell if there are
change directory commands that should only have an effect on the
other commands in the same line. Otherwise, if make is not running in
compatibility mode (for example, when -j flag is specified), commands
would be executed in a single shell and lines following the "cd" might
not work as expected.

Adjust the target script lines that use "cd" to run in a subshell
by adding appropriate parenthesis.

# HOW TO UPDATE THE ZONEINFO DATA
#
# Import the new sources to the vendor branch:
#
# $ cd ~/freebsd/src
# $ git worktree add ../tzdata vendor/tzdata
# $ pushd ../tzdata
# $ tar -xvf ../tzdata-latest.tar.gz
# (check with "git status" and "git diff" if it all makes sense)
# $ git add -A
# $ git commit -m "Import tzdata 20XXX"
# $ git tag -a -m "Tag import of tzdata 20XXX" vendor/tzdata/tzdata20XXX
# $ git push --follow-tags freebsd vendor/tzdata
# $ popd
#
# Merge-from-vendor
#
# $ git subtree merge -P contrib/tzdata vendor/tzdata
# (write a meaningful commit message)
# $ git push freebsd HEAD:main
#
# MFC
#
# $ git checkout -b freebsd/stable/12 stable-12
# $ git cherry-pick -x [hash of merge commit to main] -m 1 --edit
# (write a meaningful commit message)
# $ git push freebsd HEAD:stable/12
#
#
# If there are changes to zone1970.tab, update the baseline file by running
# `make baseline` in usr.sbin/tzsetup to check if tzsetup is able to parse new
# contents (if not, report/fix tzsetup). Check that update does not
# introduce breaking/unexpected changes to continents/countries/zones,
# and commit the updated baseline file.
