python/semanage: Enable listing file_contexts.homedirs

Include entries from file_contexts.homedirs when listing file contexts
via "semanage fcontext -l"

"semanage fcontext -l" so far ignored content of file_contexts.homedirs
file, which is confusing for users (more specific rules may be ignored in
favor of rules unseen to the user since file_contexts.homedirs has
higher priority than file_contexts).
