Title: pkg-config file for wcslib is 'wcslib.pc', not 'wcs.pc'

The `--use-system-wcslib` option uses `pkg-config` to determine the compiling and linking flags for `wcslib`, but it uses the wrong name for the pkg-config file. This patch changes the pkg-config name for wcslib from `wcs` to `wcslib`.
