git-sh-i18n.sh: add GIT_GETTEXT_POISON support
Change git-sh-i18n.sh to support the GIT_GETTEXT_POISON environment
variable like gettext.c does, this ensures that tests that use
git-sh-i18n.sh will fail under GETTEXT_POISON=YesPlease if they rely
on Git's C locale messages without declaring that they do.
