runqemu: Change nfs to mount via TCP

Since kernel commit b24ee6c64ca7 ("NFS: allow deprecation of NFS UDP protocol"),
NFS UDP has been disabled by default due to the potential data corruption caused
by fragmentation during high loads. So now we cannot boot up with nfs mode and
default kernel.

We'd better turn to use TCP accordingly.
