proposed mozilla-rootcerts fix

[Greg Troxel <gdt%lexort.com@localhost>]

Currently mozilla-rootcerts insists on the certs dir existing.  While it
should, there is currently a bug where uninstalling
mozilla-rootcerts-openssl deletes the certs dir.

This patch causes "mozilla-rootcerts install" to just create the
directory.

I have no idea why this failure case was ever coded, other than just
general precondition-checking paranoia.

jperkin@: OK to commit during freeze?
