[frogr] Check for the value of HAVE_GSTREAMER, not just its definition

[Mario Sanchez Prada <msanchez src gnome org>]

commit 6c7fa88314af46b3c50bf48bdd70e790422ab659
Author: Mario Sanchez Prada <msanchez gnome org>
Date:   Tue May 23 12:58:37 2017 +0100

    Check for the value of HAVE_GSTREAMER, not just its definition
    
    This will be useful when migrating to meson, where we will always
    define this, with different values depending on the situation.
