    build: bump ABI to sysprof-capture-4
    
    GLib will now be linking against sysprof-capture-4.a. To support that,
    sysprof had to remove the GLib dependency from sysprof-capture-4 which
    had the side-effect of breaking ABi.
    
    This bumps the dependency and includes a fallback to compile just the
    libsysprof-capture-4.a using a subproject wrap.
