libsemanage: Add file_contexts and seusers to the store

This patch writes file_contexts and seusers to the policy store as well as
/etc/selinux/. Additionally, file_contexts and seusers are now parsed from the
store rather than the final directory which was the old behavior. This allows
all policy related files to be kept in the policy store.
