[LTP] [LTP PATCH v2 3/3] nfs_lib.sh: Check running rpc.mountd, rpc.statd

[Petr Vorel]

NOTE: we're not checking rpcbind/portmap which is required for NFSv3,
as it's rpc.mountd dependency.

Deliberately not add pgrep as required dependency.

changes v1->v2:
* check for rpc.mountd, rpc.statd
(previsously checked for rpc.mountd, rpcbind/portmap)
