vala: Also add --target-glib if glib is built as subproject

Previously, meson would only check if glib was part of
target.external_dependencies and add --target-glib appropriately. This
however had the downside of meson not adding --target-glib if glib was
included as a subproject, potentially breaking otherwise builds.

Instead of checking external_dependencies, check target.added_deps for
an occurrence of 'glib-2.0' and then pick the appropriate codepath
(either from the external dependency based on version_reqs or for the
internal dependency based on the actual version, potentially downgraded
to the latest release version)
