[gtk/wip/nirbheek/gtk-3-24-meson: 46/48] tests: don't overwrite GSETTINGS_SCHEMA_DIR when running under meson

[Chun-wei Fan <fanchunwei src gnome org>]

commit 79370bcb1edfa0f43ad527ee8d79b24e109ca1ed
Author: Christoph Reiter <creiter src gnome org>

    tests: don't overwrite GSETTINGS_SCHEMA_DIR when running under meson
    
    Under autotools the compiled schemas are in the build directory and with
    meson they are in the root build dir. Avoid changing the autotools build for
    now and add a special GTK_TEST_MESON env var which we can use to differentiate
    the two.
    
    See 1253e7bfcbc80f88 for a similar fix on master.
