[gdk-pixbuf/gdk-pixbuf-2-32] Run only pixbuf-lowmem test on GNU libc

[Matthias Clasen <matthiasc src gnome org>]

commit e1fd25a3d0c18bd941f685bbdf5aa3812403a48e
Author: Natanael Copa <ncopa alpinelinux org>
Date:   Tue Oct 6 09:11:38 2015 +0200

    Run only pixbuf-lowmem test on GNU libc
    
    The test case depends on GNU libc specific internals so we only run it
    on GNU libc.
    
    This fixes build on Linux with musl libc.
