[PATCH v2 3/5] t/lib-gettext: test installed git-sh-i18n if GIT_TEST_INSTALLED is set

["Johannes Schindelin via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Johannes Schindelin <johannes.schindelin@xxxxxx>

It makes very, very little sense to test the built git-sh-i18n when the
user asked specifically to test another one.
