[rancid] Force10 FTOS 9 keeps triggering alerts due to flash mod time changing

[Thomas Vachon]

No better. Still happens on ever rancid-run.  I tried moving it to a
non-terminating regex and adding a \n with no luck.  IT seems to trip up on
the date.  Here is the exact output of dir flash:

Directory of flash:

 1  drwx       4096   Jan 01 1980 00:00:00 +00:00 .
 2  drwx       2048   Aug 02 2013 05:36:24 +00:00 ..
 3  drwx       4096   Mar 30 2012 18:16:28 +00:00 TRACE_LOG_DIR
 4  drwx       4096   Mar 30 2012 18:16:28 +00:00 CORE_DUMP_DIR
 5  d---       4096   Mar 30 2012 18:16:28 +00:00 ADMIN_DIR
 6  drwx       4096   Jul 31 2013 11:55:02 +00:00 CONFIG_TEMPLATE
 7  -rwx      16712   Jul 31 2013 11:53:56 +00:00 startup-config
 8  drwx       4096   Jul 31 2012 09:38:16 +00:00 RUNTIME_PATCH_DIR
 9  -rwx      16351   Jun 19 2013 10:26:30 +00:00 startup-config.bak

Looking at dir flash:/.. it is actually the / mount of the FTOS OS, which
is getting modified by a log entry for the login as far as I can tell.
