Add pkgconfig files for libsepol, libselinux, and libsemanage.

Having a pkgconfig files allows the pkg-config tool to be used to
query the presence of the library (or a particular version of it),
and to obtain the C flags and linker arguments to build with it.

Based on Debian patches by Manoj Srivastava <srivasta@debian.org>.
