keyctl: use printuid for printing UID/GID

UID/GID are unsigned except special -1 value (which is also special in
context of specific keyctl commands), so special printing function
should be used.

* keyctl.c (keyctl_chown_key, keyctl_get_persistent): Use printuid
instead of printf with "%d" conversion for printing UID/GID.
