install nfs modprobe config file

For nfs4, in case nfs.ko is not loaded mount.nfs4 will try to load
nfs4.ko instead of nfs.ko. Fedora nfs-utils creates a lib/modprobe.d/nfs.conf
in which there's below alias:
alias nfs4 nfs

Dracut also need this file to auto load nfs kernel module.

Tested booting to a fedora 17 nfsroot share.
