[Intel-gfx] [PATCH i-g-t] meson: Add fallback for xmlrpc discovery

[Arkadiusz Hiler]

Since Debian-likes (including Ubuntu) ship xmlrpc packages predating the
pkg-config era, we need to use xmlrpc-c-config to do the discovery.

Also this patch adds HAVE_CHAMELIUM flag to config.h to get rid of
"implicit declaration of function" warnings in case of meson build.
