package/gstreamer1/gstreamer1: add introspection support

If gobject-introspection is selected, explicitly set -Dintrospection=enabled in
the configure options and add a dependency for gobject-introspection.

This feature requires an upstream patch that allows introspection support even
when cross-compiling.

+Subject: [PATCH] meson: build gir even when cross-compiling if introspection
+ was enabled explicitly
+
+This can be made to work in certain circumstances when
+cross-compiling, so default to not building g-i stuff
+when cross-compiling, but allow it if introspection was
+enabled explicitly via -Dintrospection=enabled.
+
+Fixes #454 and #381.
