[gnome-settings-daemon/wip/gcr4] build: Use gcr4 by default, but have an option to use gcr3 too

[Milan Crha <mcrha src gnome org>]

commit 6aab0f5f45f73bf0c29577e44e7477852dde57cd
Author: Milan Crha <mcrha redhat com>

    build: Use gcr4 by default, but have an option to use gcr3 too
    
    The gcr4 replaces gcr3, thus make it possible to use either of the two,
    while defaulting to gcr4, as it'll live for a longer time.
