kernel configs: enable NFS client on the 3 kernels that lacked it (NFS rootfs)

A scan for NFS-root capability found 3 of 107 kernel configs with no NFS client
at all, so a board on those kernels can't mount an NFS root (the initramfs has no
nfs.ko to load):

  - linux-rockchip-vendor          (network-filesystems menu was off)
  - linux-sun55iw3-syterkit-legacy (no network-filesystems lines)
  - linux-sun60iw2-vendor          (# CONFIG_NFS_FS is not set)

Enable CONFIG_NETWORK_FILESYSTEMS + CONFIG_NFS_FS=m (+ NFS_V3_ACL, NFS_V4),
matching the mainline configs. NFS_V3 comes on by default; the initramfs (BOOT=nfs)
brings up the NIC, so IP_PNP isn't required. Every kernel config now ships an NFS
client.
