[Buildroot] [git commit] package/petitboot: use default logfile dir

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=12e964302174dd299a6ce48fb3f6c349c45dd718
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

All the petitboot components assume /var/log/petitboot by default;
pb-console can also put multiple logs there and pb-sos collects that
directory when creating a diagnostic tarball.

Defer to this default when launching pb-discover. If someone wants to
override, let's call the file /etc/default/petitboot which makes more
sense to be shared by all the components.
