logd: refactor LastLogTimes a bit

There's still plenty of work that can be done here, particularly
re-doing the locking so each LogReaderThread does not mutually exclude
the others, but that's out of the scope here.

This change primarily removes the public 'mTimes' from LogBuffer and
creates a new LogReaderList class instead.  It would have merged this
into LogReader, but that creates a circular dependency.

This change also removes the need to reference LogReader or
LogReaderList from LogAudit, LogKLog, and LogListener, instead relying
on LogBuffer()::log() to call LogReaderList::NotifyNewLog().

Test: logging unit tests
