[PATCH 4/5] libselinux: fix memory leak in getconlist

[Nicolas Iooss <nicolas.iooss@xxxxxxx>]

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.
