This commit switches to use the new gettext logic, which involves:
- using TARGET_NLS_DEPENDENCIES instead of hand-encoded dependencies
on gettext/host-gettext
- pass --with-libintl-prefix only when a separate libintl library is
available
- dropping BR2_PACKAGE_GETTEXT selection
- removing a musl-specific workaround. Indeed, when NLS is enabled,
we now have the full-blown libintl, even with the musl C library
