support schema files from third-party plugins

Allow upgrade process to include schema files from third-party plugins
installed in /usr/share/ipa/schema.d/*.schema.

The directory /usr/shar/eipa/schema.d is owned by the server-common
subpackage and therefore third-party plugins should depend on
freeipa-server-common (ipa-server-common) package in their package
dependencies.
