system/nxinit: add rptun and unlink builtin commands

Browse source 
BL uses init framework (not NSH), so the NSH rptun command is not
available. Add rptun as an init builtin command that supports
start and stop subcommands. Also add a generic unlink builtin
command for removing device nodes.

Usage in init.bl.rc:
  rptun stop /dev/rptun/corecs
  unlink /dev/rptun/corecs
  rptun start /dev/rptun/corecs

- rptun start/stop: open device, ioctl(RPTUNIOC_START/STOP), close
- unlink: generic command to unlink any file/device node
