David reports that dhclient-script(8) on Fedora needs a number of binaries that are not included in PROGS of the current mbuto profile, and we would also need to include hostnamectl(1) there, which will fail without a systemd init. Embed a minimal script for dhclient(8) in the profile itself, written to /sbin/dhclient-script at boot, to just check what we need to check out of DHCP and DHCPv6 functionality. While at it, drop busybox and logger from PROGS, as we don't need them, and add hostname(1). While DHCP option 12 isn't supported yet by the DHCP implementation in passt, we should probably add it soon. Note: owing to the simplicity of this script, we now need to bring up the interface before starting dhclient: add this in test scripts where it's not the case yet.
