[boot]: Changes to upstartify more of our init scripts.

This changes many of our upstart jobs to use upstart
properly rather than just running the corresponding
scripts in /etc/init.d. The init.d scripts all pull in
helper functions, etc that are mostly unused. These
changes typically go from using many subshells to start
a daemon to a single exec of the daemon with proper
tracking by upstart. Most of these jobs are not in
the critical boot path, but we should still keep them
as optimized as possible.
