strace: Handle variable-width timestamps

If a machine has an uptime of over 10 million seconds (about 4 months),
then the timestamp field grows.  Strace couldn't handle this, since it
assumed the field was 40 bytes.

Incidentally, the machine wasn't up for 120 days, but it might have not
been turned off in that long.  Sometimes (often?) soft reboots don't reset
the TSC, which is where that timestamp comes from.  This occurence is the
same reason I found the bug from commit fd20de73987b ("Fixes TCP drops due
to ARP timeouts").
