[iptables PATCH 2/8] xtables-monitor: Flush stdout after all lines of output

[Phil Sutter <phil@nwl.cc>]

Writing an xtables-monitor testsuite is pretty much impossible without
this due to unreliable output flushing. Just move the fflush() call from
trace_cb() to its caller so monitor events benefit from it as well.
