hostname: generate a uniqe hostname on boot

This will generate a hostname based on machine name and serial number.
(E.g. colibri-imx7-031111777)
If serial number is not found it will say "no-serial-number" in host
name.
If machine is not supported hostname will include "unsupported-device"
string.
If /dev/device-tree does not exist it will say "recovery-mode"
as it assumes its in recovery mode of Toradex Easy Installer

To prevent openembedded from creating /etc/hostname file
add hostname_pn-base-files = "" to configration
