[f-spot] Add --with-gnome-screensaver-themesdir=DIR

[Stephane Delcroix <sdelcroix src gnome org>]

commit 16f08070d7fb48fc096a9cfbca962c96d6a71661
Author: Loïc Minier <lool dooz org>

    Add --with-gnome-screensaver-themesdir=DIR
    
    Add support for --with-gnome-screensaver-themesdir=DIR and merge the
    GNOME_SCREENSAVER_THEMESDIR= computing logic into the new AC_ARG_WITH.
    This allows overriding the default GNOME_SCREENSAVER_THEMESDIR when no
    gnome-screensaver bits are installed and is consistent with the other
    options.
