media-libs/qhull: re-add static-libs + various fixes

CMakeLists.txt claims some libraries are intended to be static-only
and so weren't installed.

Shared:
- libqhull.so (deprecated, but needed by matplotlib)
- libqhull_r.so

Static-only:
- libqhullcpp.a (needed by at least prusaslicer)
- libqhullstatic.a
- libqhullstatic_r.a

Also:
- install missing deprecated qhull.pc
- install cmake/pc files in right libdir
- fix double prefix in pc files
