nfsroot: set tcp as the default transport protocol
UDP is disabled by default in commit b24ee6c64ca7 ("NFS: allow deprecation of NFS UDP protocol"), but the default mount options is still udp, change it to tcp to avoid the "Unsupported transport protocol udp" error if no protocol is specified when mount nfs.
