That should be avoidable by modifying f5rancid to ignore those checksum 
lines in the subroutine that handles the output of the command that 
produces them.  Unfortunately I know nothing about them so can't even 
begin to suggest where that is, but taking a look at the code now there's 
a similar example:

# This routine parses "bigpipe db show"
sub ShowDb {
    my($line) = (0);
    print STDERR "    In ShowDb: $_" if ($debug);

    while (<INPUT>) {
        tr/\015//d;
...
        /UCS.LoadTime/ && next;
        /Configsync\..*Time/ && next;

Here, lines matching /UCS.LoadTime/ and /Configsync\..*Time/ are skipped.  
So I guess you need a similar line, in the appropriate sub, to skip lines 
matching /Binary configuration captured, checksum:/.
