init: Adding lspci description in log file

When debugging a remote system, understanding the PCI configuration
could be useful.

Adding lspci reporting inside the log file
detect: Avoid temp. detection failure on 9+ cores CPUs

If a CPU having more than 9 cores, the crit_alarm entry in sysfs is
shorten in a 17 char long string like : "temp12_crit_alar"

This patch is so ensuring that we try a shorten string if such case but
also harden the case when some sensors entries are missing (? does this
exists really ?)
base: Don't search debootstrap for all distro

If you aims at building rpm based roles, there is no need to check if
debootstrap is installed.

This is a remain of the legacy code when it was deb specific. Since we
can also build rpm-based distro, let's only check for debootstrap when
considering the .deb case.
