[rancid] Nexus 9K support in RANCiD 3.7

[David Chapman]

I like this fix.  I had a similar problem on NXOS based FC switches but opted to have it just not list out the logflash.

    We recently outfitted a new office with Cisco Nexus 9000s.  I monitor router and switch configuration changes enterprise-wide with custom built RPM packages of RANCiD on RHEL7 with git and gitweb.

    The 9Ks have a constantly changing file date on a subfolder that can't be controlled:

    - !Flash: logflash:       69632    Dec 29 01:37:09 2017  debug_logs/
    + !Flash: logflash:       69632    Dec 29 02:42:52 2017  debug_logs/

    The following code patch to v7 prevents this from generating hourly commits and emails.

    There's also a problem with a constantly fluctuating memory size value, but I haven't figured out how to fix that.

    Thank you Heasley and co-conspirators for a great tool!
