[PATCH xserver] meson: Define DEFAULT_LIBRARY_PATH as join_paths(get_option('prefix'), get_option('libdir'))

[Aaron Plattner]

'libdir' defaults to 'lib', so running X -showDefaultLibPath just prints 'lib'
instead of '/usr/lib' or '/usr/local/lib'. Use joint_paths() to get the correct
full path.

The NVIDIA driver installer noticed this meson vs. autoconf difference:

WARNING: You appear to be using a modular X.Org release, but the X library installation path, 'lib', reported by `/usr/bin/X -showDefaultLibPath` does not exist. 
         Please check your X.Org installation.
