mutter: Fix build without remote desktop support

The clipboard session is always built, as input capture uses it, but
the remote selection source it calls into was only built with
-Dremote_desktop=true, so libmutter failed to link with the default
PACKAGECONFIG:

  ld.lld: error: undefined symbol: meta_selection_source_remote_new

Build the remote selection source unconditionally.

+Subject: [PATCH] build: Build remote selection source without remote desktop
+
+meta-clipboard-session.c is built unconditionally, as input capture
+uses it, but it calls into meta-selection-source-remote.c, which is only
+built with remote desktop support. Linking libmutter with
+-Dremote_desktop=false fails:
+
+  ld.lld: error: undefined symbol: meta_selection_source_remote_new
+
+The remote selection source has no remote desktop dependencies, so
+build it unconditionally as well.
