core: link user keyring to session keyring (#6275)

Commit  74dd6b515fa968c5710b396a7664cac335e25ca8 (core: run each system
service with a fresh session keyring) broke adding keys to user keyring.
Added keys could not be accessed with error message:

keyctl_read_alloc: Permission denied

So link the user keyring to our session keyring.
