MFC r339818: rcorder(8):

  Add support for /etc/rc.resume, so it calls
  "rcorder -k resume" and runs scripts containing "KEYWORD: resume"
  with single "resume" argument.

  Working example is the port sysutils/cpupdate that defines
  extra_commands="resume" to reload CPU microcode cleared
  by suspend/resume sequence.

  This change does nothing for a system having no scripts with
  KEYWORD: resume.
