postinstall installs obsolete files

Hi,

I just noticed that postinstall on a particular machine wanted to remove 
obsolete certs, plus it also wanted to do a certs rehash. I wondered which 
it'd do first, so I ran what it suggested, and saw it ran 
opensslcertsrehash first.

Afterwards:

ls -l /etc/openssl/certs/ | wc
      298    3265   35316
certctl rehash
ls -lt /etc/openssl/certs/ | wc
      295    3232   34856

Perhaps postinstall should run obsolete before opensslcertsrehash?
