syscall_entering_trace: set TCB_FILTERED along with TCB_HIDE_LOG

This allows to remove some of hide_log() checks that became redundant.

* syscall.c (syscall_entering_trace): Set TCB_FILTERED along with
TCB_HIDE_LOG, remove now redundant hide_log(tcp) check.
(syscall_exiting_decode): Replace "filtered(tcp) || hide_log(tcp)"
with "filtered(tcp)".
