Move start of nyx-utils to boot-done

:Release Notes:
nyx-utils takes several seconds to complete, and the resulting files
are not accessed until 10+ seconds after the 'boot-done' event.

:Detailed Notes:
Sangwoo Kang made some excellent measurements related to nyx-utils
and found the numbers I quoted above.  These clearly demonstrate
that nyx-utils can be moved to a very late spot in the boot
sequence.

:Testing Performed:
miniBAT on verification build

:QA Notes:

:Issues Addressed:
[GF-46288] Move start-on event for nyx-utils.conf to boot-done
[GF-54344] CCC: nyx-utils=14,v1.0.1
