Subject: [PATCH] [GStreamer] Build broken when using GStreamer 1.27.2 built
 from tarballs https://bugs.webkit.org/show_bug.cgi?id=299656

Reviewed by Xabier Rodriguez-Calvar.

gst_pad_probe_info_set_buffer() will ship in GStreamer 1.27.3 which hasn't been released yet. So
when building against 1.27.2 use our internal implementation. Also make sure builds against current
GStreamer git main still work, by checking the full (including nano) version.
