libselinux: fix memory leak in getconlist

Browse Source 
In getconlist.c's main(), "level" is duplicated from an optional
argument without being ever freed. clang's static analyzer warns about
this memory leak.

Free the allocated memory properly in order to remove a warning reported
by clang's static analyzer.
