runqemu: support multiple qemus running when nfs

Fixed:
* In build1:
  $ runqemu nfs qemux86-64
  In build2:
  $ runqemu nfs qemux86-64

  It would fail before since the port numerbs and conf files are
  conflicted, now make runqemu-export-rootfs work together with runqemu to
  fix the problem.

* And we don't need export PSEUDO_LOCALSTATEDIR in runqemu, the
  runqemu-export-rootfs can handle it well based on NFS_EXPORT_DIR.

* Remove "async" option from unfsd to fix warning in syslog:
  Warning: unknown exports option `async' ignored

* Fixed typos

Both slirp and tap can work.
