meson: Fix deprecation warning for pkgconfig
Just a minor thing that was bugging me which should probably make it in for the next release. I've tested this with Meson 0.47 (weston's advertised minimum) and 0.49.1 (current), and they generate identical and correct pkgconfig files.
Meson 0.49 now issues a warning for libraries being passed into the 'libraries' keyword argument. Now they should be passed as a positional argument.
