i18n: git-status basic messages

Gettextize the most common git-status messages. Many tests checked for
these explicitly. Change them to skip under GETTEXT_POISON=YesPlease.

Some of the tests in t7508-status.sh needed to be split up when I
added C_LOCALE_OUTPUT to them, since parts of them affected later
tests (some of which aren't being skipped) indirectly.
