[klibc] [patch] nfsmount fix rpc header length

[maximilian attems]

nfsmount sends bad rpc header in portmap calls. The length in rpc header
should be only the length of  data without header (nfsmount sends the
length including 4 byte header). Portmap in Fedora 7 does not like this.
This change in sunrpc.c:rpc_header fixed it
see http://bugs.debian.org/428832
