Crash from swift-drive-audit when no date at the beginning of kern.log line

[Jola Mirecka]

Sometimes there is no date at the beginning of a line in kern.log. This may be caused by '\n' character in the text of a previous line. For example:

Feb 27 16:49:44 sw-aw1st13-object0001 kernel: imklog 5.8.1, log source = /proc/kmsg started.
libgcc_s.so.1 must be installed for pthread_cancel to work << no date!

Although it does not happen often, there should be a check ensuring the program doesn't crash in case this situation occurs.
