  Log Message:
  -----------
  tracer: Mask buggy gcc 9.x warnings on Ubuntu 20.04

In function ‘strncpy’,
    inlined from ‘trace_slreply_out’ at tracer.c:2290:2:
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:106:10: warning:
    ‘__builtin___strncpy_chk’ output may be truncatedl copying between
    1 and 21 bytes from a string of length 153 [-Wstringop-truncation]

This is a false positive, since the "153" bytes are actually 7 * 22
bytes, packed as a (char **) array of 7 buffers.  So just mask the
warning for now, just at "tracer" module level.
