[mutter/gbsneto/tracing-fixups: 2/2] backend: Conditionally compile MetaProfiler

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 57945a730f39113a23794896b98dd75880edec11
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>

    backend: Conditionally compile MetaProfiler
    
    MetaProfiler is not built when -Dprofiler=false, and that
    breaks the build since MetaBackend unconditionally imports
    and uses it.
    
    Fix that by wrapping MetaProfiler in compile-time checks.
