Allow su to access virtualization

Use our standard macro for granting all the necessary permissions
instead of copying a part of it.

Add ioctl access for all clients for Unix stream sockets & pipes; this
allows them to be used for stdin/stdout without triggering
denials. (Only unpriv_sock_ioctls can be used.)

Together this allows a root shell to use `vm run` without getting
spurious denials such as:

avc:  denied  { ioctl } for  comm="crosvm" path="socket:[835168]"
dev="sockfs" ino=835168 ioctlcmd=0x5401 scontext=u:r:crosvm:s0
tcontext=u:r:su:s0 tclass=unix_stream_socket permissive=0
