libsemanage: Add ability to extract modules

Add semanage_module_extract() to extract a module as CIL or HLL. The
function takes a module name and whether to extract as CIL or HLL.

If a CIL file is requested, but does not exist, semanage_module_extract()
will compile the HLL to CIL and cache the CIL in the store as well as
extract the module. A module that was installed from a CIL file will export
as CIL when the HLL version of the file is requested.
