media-libs/gst-plugins-bad: avoid automagic dep on libva

As noted on the bug, I need to discuss properly with leio whether or not the
split for -va makes sense, but -va is an orphan/leaf package right now so it's
lower priority than just fixing -bad which many people have installed. So, for now,
just backport the relevant upstream patches to fix the automagic for this side.

+Subject: [PATCH 1/2] meson: Fix libdrm and vaapi configure checks
+
+We do not need fallback: for libdrm checks because the wrap file
+already has a [provide] section.
