ss: fix file-based filtering segfault

Commit 1527a17 introduced a change where the second of two ssfilter_parse()
calls in ss.c was moved outside of a conditional block (ss.c: ~3575). This
commit enabled the parsing of services, such as 'sport = :ssh', but
inadvertently broke the '-F' file-based filtering:
