The two memory leaks were found with the test suite running in
--enable-valgrind mode - here are the relevant error messages:
For fwknopd server GPG clean up:
==345== 9 bytes in 1 blocks are definitely lost in loss record 2 of 2
==345== at 0x4C2815C: malloc (vg_replace_malloc.c:236)

For fwknop client rc file processing:

There is also a new clean_exit() function that makes it easier to ensure that
resources are deallocated upon existing.
