eventlog: Added comment for powerd_suspend dependency

powerd_suspend calls the eventlog script to update the mosys eventlog
snapshot on every resume.  Added comment noting this dependency.

TEST=do a suspend-resume cycle. Then open up "eventlog" under
chrome://system.  The last entry in eventlog should correspond
to the resume that just happened.
