[PATCH] Policycoreutils: Make pkg-config work for more types of builds

[James Carter <jwcart2@gmail.com>]

To support static builds, pkg-config is used to add the libraries
needed for libselinux and libsemanage during the build. Unforunately,
pkg-config will always use the installed pc files for libselinux and
libsemanage.

Instead set PKG_CONFIG_PATH when invoking pkg-config so that
it searches in order:
1) The directory specified by PKG_CONFIG_PATH, if already set.
2) The local src directories of libselinux and libsemaange.
3) The default directories specified by the system.
