s390/uvdevice: Add 'List Secrets' UVC
Userspace can call the List Secrets Ultravisor Call
using IOCTLs on the uvdevice. The List Secrets UV call lists the
identifier of the secrets in the UV secret store.
The uvdevice is merely transporting the request from userspace to
Ultravisor. It's neither checking nor manipulating the request or
response data.
