It is not unusual that projects can target multiple boards, and in
such cases, a lot is shared between boards and only the low-level
stuff differ.
Allow users to specify more than one dracut config file to cover
tose cases.
dracut does not accept more than one config file with the -c option,
but it can load more than one from a directory with --confdir. So,
we copy all the config files to a temporary directory and se that as
--confdir. However, we can't drop passing -c, or dracut would read
the system-wide /etc/dracut.conf (not sure if ${prefix} is even used),
which we do not want. So, we use an empty file as -c; /dev/null comes
in handy as an empty file.
