Patchwork netbase: merge init script updates from upstream

* Read /proc/mounts only once.
* Support many more network filesystem types.
* Remaining differences to netbase 4.47:
  - Uses the mountvirtfs keyword instead of mountkernfs
  - Doesn't use lsb functions
  - Doesn't print a warning if /etc/network/options exists
  - Doesn't use --exclude parameter for ifup, because
    busybox doesn't support it.
