wayland: rebase pkgconfig patch for 1.25.0

The 00-fix-wayland-scanner-pkgconfig.patch was anchored on a context
line ('bindir=' + join_paths(...)) that Wayland removed between 1.24
and 1.25. After our F0 bump to 1.25.0 the unpack step rejected the
patch and aborted the build_compat arm pass.

Pull the rebased patch from ROCKNIX (commit a9e464274a in their
graphics/display sync) where the same context shift was already
resolved: the bindir line is gone, the filebase line stays.
