Port Universal Time settings to strict POSIX

* build-aux/announce-gen, build-aux/bootstrap:
* build-aux/do-release-commit-and-tag, build-aux/git-version-gen:

* build-aux/update-copyright, build-aux/useless-if-before-free:
* build-aux/vc-list-files, tests/test-strftime.c:
Use TZ="UTC0", not TZ="UTC".  Either works on GNU platforms,
but POSIX says the behavior of TZ="UTC" is undefined.
