Peter Korsgaard 7a3f85ddff ifupdown-script: send current hostname in DHCP request
For the default (BR2_SYSTEM_DHCP) /etc/network/interfaces handling.

Both the "big" and busybox ifupdown variants pass the hostname argument to
the DHCP client through the shell, so we can use $() to expand to the
current hostname value.

Notice that this may not be handled by all DHCP clients.
