libsepol: add patch to make the build process more standard

Patch the Makefiles to make PREFIX and DESTDIR follow standard
semantics to get rid of DESTDIR during compile time in
libsepol.mk and generate proper pkg-config files.

+libsepol: build: follow standard semantics for DESTDIR and PREFIX
+
+This patch solves the following issues:
+- The pkg-config files generates odd paths when using DESTDIR without PREFIX
+- DESTDIR is needed during compile time to compute library and header paths which it should not.
+- Installing with both DESTDIR and PREFIX set gives us odd paths
+- Make usage of DESTDIR and PREFIX more standard
