[yocto] [meta-selinux][PATCH 1/2] refpolicy: split do_install to three steps

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

Split do_install() to:
  + prepare_policy_store()
  + rebuild_policy()
  + install_misc_files()

This allows to make partial change to do_install() instead of re-write
it totally from specific refpolicy bb file.
