[LTP] [PATCH 2/3] nfs_lib.sh: Check running rpc.mountd, rpcbind/portmap

Hi Alexey,

I found that at least some tests (e.g. nfs01) runs with stopped rpcbind.
I suppose that's because nfs-server.service is able to restart it
(it's activated via socket).

Although rpc.mountd (nfs-mountd.service) is required, nfs-mountd.service is a
nfs-server.service dependency (nfs-server.service:Requires=nfs-mountd.service).
Thus it's probably enough to check that rpc.nfsd is running.
=> sending v2 with just single commit.

Kind regards,
Petr
