Fixes test: validate.uridecodebin.expose_raw_pad_caps testsrcbin (currently part of debugutilsbad) is an useful element for validate tests. validate.uridecodebin.expose_raw_pad_caps makes use of it. Unfortunately, because validate tests with GStreamer only run with whitelisted plugins and `debugutilsbad` wasn't in the whitelist, the test was failing and being auto-skipped. This patch adds debugutilsbad to the whitelists used by validate tests in subprojects with a validate/meson.build. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4931>
