[gjs] Allow aborting when running out of memory

[Johan Bilien <jobi src gnome org>]

commit 0bf18867ec7f5cc69b6ec59026fede38d2380d9b

    Allow aborting when running out of memory
    
    Aborts if GJS_ABORT_ON_OOM is set.
    
    Since glib is aborting on failed malloc, we probably want to do the same
    on failed JS_malloc, rather than continuing in an undefined state.
