api: disallow virDomainSaveImageGetXMLDesc on read-only connections
The virDomainSaveImageGetXMLDesc API is taking a path parameter,
which can point to any path on the system. This file will then be
read and parsed by libvirtd running with root privileges.
Forbid it on read-only connections.

Upstream commit 12a51f372 which introduced the VIR_DOMAIN_SAVE_IMAGE_XML_SECURE
alias for VIR_DOMAIN_XML_SECURE is not backported.
Just skip the commit since we now disallow the whole API on read-only
connections, regardless of the flag.
The virtlogd daemon's only intended client is the libvirtd daemon. As
such it should never allow clients from other user accounts to connect.
The code already enforces this and drops clients from other UIDs, but
we can get earlier (and thus stronger) protection against DoS by setting
the socket permissions to 0600

admin: reject clients unless their UID matches the current UID
The admin protocol RPC messages are only intended for use by the user
running the daemon. As such they should not be allowed for any client
UID that does not match the server UID.
