you can
1) the device shouldn't be repeatedly altering the file; its a bug.  upgrade 
the o/s and/or complain to crisco.
2) edit etc/rancid.types.base to remove dir show flash or, since the install
of the next version that you adopt will overwrite that file, define your own
type just for asa in rancid.types.conf.  i prefer the latter as it doesnt
discourage you from adopting new versions.
3) edit lib/ios.pm as you would have changed rancid or, since the install ...,
create a new lib/your.pm with your own function to filter show flash and
use that in rancid.types.conf.
