gettext tests: add detection for is_IS.ISO-8859-1 locale

Add a GETTEXT_ISO_LOCALE prerequisite to lib-gettext.sh, it'll be set
if we have an is_IS.ISO-8859-1 locale.

This is needed for an upcoming test that checks if our gettext library
can recode our UTF-8 po/is.po to is_IS.ISO-8859-1 on request.
