[bug#53933] [PATCH 2/3] status: Use bold more sparsely at -v1.

[Ludovic Courtès]

Until now, at -v1, all the "apply N grafts" messages (for instance)
would be displayed in bold.  This would typically result in several
subsequent lines all bold, although none of them is particularly
interesting.  This improves on that by avoiding bold at -v1 for these
messages.

* guix/status.scm (print-build-event)[emph]: New variable.
Use it for the "View build log", "expected hash", and "offloading build"
messages.
[info]: Default to 'identity' when PRINT-URLS? and PRINT-LOG? are both
false.
