src: Define X11_LOCALEDATADIR for BSD Compose data

FreeBSD and NetBSD have X11 locale Compose data directories in
${X11_PREFIX}/lib/X11/locale instead of ${X11_PREFIX}/share/X11/locale:
https://github.com/freedesktop/xorg-lib-libX11/blob/20a3f99/configure.ac#L336-L340

BUG=https://github.com/ibus/ibus/pull/2478
