Add macOS EOL

Apple doesn’t disclose when it stops providing security updates for
macOS versions. There’s no consensus on when the exact EOL date is.

Lacking that information, I applied the following ruleset, which is
driven by what people have observed, and seems pragmatic enough:

- From Mac OS X 10.0 through 10.4, a version 10.N would be considered
  EOL on the day the first patch-level update 10.(N+2).1 for its
  N+2 successor was released.

- Starting with 10.5, Apple began to support three versions at the same
  time. For 10.5 itself, the EOL date is difficult to pin down so I
  went with 2011-06-23, the date given by the English-language
  Wikipedia.

- From 10.6 through 10.11, a version 10.N would be considered EOL on
  the day the first patch-level update 10.(N+3).1 for its N+3 successor
  was released.

- Starting with macOS Sierra (10.12), Lynis counts the patch level.
  Any version 10.N.P can be considered EOL on the day 10.N.(P+1)
  is released. If that hasn’t happened, the EOL date is the day
  10.(N+3).1 is released. If neither has been released, 10.N.P has
  no EOL date.
