suppresses %clay file-change printfs for initial filesystem

[joemfb]

This is not a pressing issue -- consider it a UX feature request.

I've long found these printfs to be superfluous, but it's gotten much worse (imo) with the growth of userspace. This is really highlighted when you boot ships in :aqua.

The printfs are replaced with

clay: committed initial filesystem (hoon)

for base/1, and

clay: committed initial filesystem (all)

for base/2

I think this is a good change. lib/ph.hoon uses these printfs to guess when the ship has finished booting, which is why CI is failing. You should be able to just switch the line that searches for "/base/2/web/"... to the new printf.

"committed"

Thanks.

It looks like the %child-sync test hung again, but this time in the "push" build instead of the "pr" build. I don't think that's related to my changes, but it's hard to be sure. Any tips on debugging these?
