pfc: fix PFC export hang on prioritized syscall with no rules (GH issue #117)

github user @varqox reported that generating PFC will hang if the
libseccomp filter contains a syscalle with a priority but no rule
set.  The root cause is the while() loop in gen_pfc.c that walks
through the filter's syscalls.  It  wasn't properly advancing
through the list when p_iter was invalid.
