[PATCH 2/2] perf/ui/gtk: Fix gtk2 build

[Jiri Olsa]

Ravi Bangoria reported issue when detecting gtk2 on Fedora 31,
where some types got deprecated:

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

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