sys-libs/glibc: ignore locale settings in preinst test

When upgrading to a new version, the localedata format might have
changed, which means the test programs may crash inside of glibc
when trying to parse it.  Since this test is not for verifying
localedata (which we'll be rebuilding anyways), clear the active
locale settings.
