MFC r285742:

  Unbreak "last reboot".

  According to the last(1) man page, the "reboot" pseudo-user should
print
  all system reboot entries. This got broken by the utmpx import, as
  records are typed.

  Re-add support for "last reboot" by specifically matching against
  SHUTDOWN_TIME and BOOT_TIME records.
