[folks] Always append to AM_VALAFLAGS, don't replace

[Simon McVittie <smcv src gnome org>]

commit f574cc5631526dc2d026fb109b6188e539123694
Author: Simon McVittie <simon mcvittie collabora co uk>
Date:   Tue Mar 12 13:50:56 2013 +0000

    Always append to AM_VALAFLAGS, don't replace
    
    This avoids losing --target-glib=2.24 (from configure.ac) in certain
    test modules.
