perf/ui/gtk: Fix gtk2 build

Ravi Bangoria reported an issue when doing the gtk2 feature detection on
Fedora 31, where some types got deprecated:

  /usr/include/gtk-2.0/gtk/gtktypeutils.h:236:1: error: ‘GTypeDebugFlags’ is deprecated [-Werror=deprecated-declarations]
    236 | void            gtk_type_init   (GTypeDebugFlags    debug_flags);

Fix this for perf by allowing the compile to pass with deprecated
symbols via the -Wno-deprecated-declarations compiler directive.
