[rancid] [PATCH] ignore ASA log files in ShowFlash

[Erik Muller]

With ASA 9.8 running on FTD2100s, there are a bunch of log files included in "show flash" that are regularly appended and archived, which makes for a lot of noise in diffs. 
- !Flash: 537549601  38345       Feb 14 2019 22:54:53  log/ssp_tz/ssp_tz.log.4.gz
- !Flash: 537549599  38703       Feb 13 2019 17:30:00  log/ssp_tz/ssp_tz.log.5.gz
+ !Flash: 537549601  38345       Feb 14 2019 22:54:53  log/ssp_tz/ssp_tz.log.5.gz
+ !Flash: 537549611  38412       Feb 16 2019 04:24:48  log/ssp_tz/ssp_tz.log.4.gz
...
- !Flash: 268440067  81510       Feb 19 2019 15:38:53  log/ssp_ntpd/ssp_ntp.log
+ !Flash: 268440067  87698       Feb 19 2019 23:38:39  log/ssp_ntpd/ssp_ntp.log


The attached patch adds them to the list of files where properties should be ignored, giving a nice stable output.

thanks,
