networkmanager: re-implement the vala detection

The introduction of DISTRO_FEATURES_OPTED_OUT allows rewriting the
DISTRO_FEATURES by removing whatever is in DISTRO_FEATURES_OPTED_OUT
from DISTRO_FEATURES.

Thus, the logic of vala can be negated, and it can changed be to
see if gobject-introspection-data is available in DISTRO_FEATURES.
