Remove ipa-ca.crt from systemwide CA store on client uninstall and cert update

The file was used by previous versions of IPA to provide the IPA CA certificate
to p11-kit and has since been obsoleted by ipa.p11-kit, a file which contains
all the CA certificates and associated trust policy from the LDAP certificate
store.

Since p11-kit is hooked into /etc/httpd/alias, ipa-ca.crt must be removed to
prevent certificate import failures in installer code.

Also add ipa.p11-kit to the files owned by the freeipa-python package.
