bit: migrate to boneyard (#10500)

Currently bit tries to automatically update daily after install
and there is apparently no way to change this potentially insecure
behavior that is contrary to Homebrew's version-based release
system and general security principles.

This problematic autoupdating mechanism was identified in the past,
but was mistakenly believed to have been resolved in the
corresponding PR. However, it was not, and until measures are taken
to address this issue it would be inappropriate to continue
distributing this software in its current state.
