gnu: mutter: Fix build.

With newer versions of Mesa, a test in ensure_bits_initialized fails.  Fixed
upstream in newer versions of mutter.  See
<https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3047>.

* gnu/packages/gnome.scm (mutter)[source]: Add patch.
* gnu/packages/patches/mutter-fix-inverted-test.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.

+Subject: [PATCH 2/5] cogl/gl-framebuffer: Fix inverted test in
+ ensure_bits_initialized()
+
+Cogl's feature COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS is required
+to use the GL_FRAMEBUFFER_ATTACHMENT_* queries.
+
+Unfortunately, the test for the availability of the private feature is
+actually inverted in ensure_bits_initialized() which causes that whole
+portion of code to be ignored, falling back to the glGetIntegerv()
+method which isn't supported in core profiles.
+
+As Mesa has recently started to be more strict about these, this causes
+the CI tests to fail in mutter.

+Subject: [PATCH 3/5] cogl/gl-framebuffer: Match testing features
+
+The function ensure_bits_initialized() in cogl-gl-framebuffer-fbo.c
+checks for COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS whereas the same
+in cogl-gl-framebuffer-back.c simply checks for the driver being
+COGL_DRIVER_GL3.
+
+Change the later to use the COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS
+flag as well.

+
+glGetIntegerv() with GL_RED_BITS/GL_GREEN_BITS/GL_BLUE_BITS/etc. is not
+supported with the GL core context, so there is no point in falling back
+to that without supporting COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS,
