checkpolicy: new package

[Thomas:
 - Indicate in the Config.in help text that this policy compiler is
   SELinux related.
 - Rewrap Config.in help text and remove trailing white space.
 - Add a comment in the .mk file to indicate why we're passing
   DESTDIR= at build time.]

+	bool "host checkpolicy"
+	help
+	  checkpolicy is the SELinux policy compiler. It uses libsepol
+	  to generate the binary policy. checkpolicy uses the static
+	  libsepol since it deals with low level details of the policy
+	  that have not been encapsulated/abstracted by a proper
+	  shared library interface.
