Bug#584583: initramfs-tools: configure_networking function: repeatedly makes DHCP requests

[Vagrant Cascadian <vagrant@freegeek.org>]

thanks to Petter Reinholdtsen, i think i've figured out the initramfs-tools
portion of this problem (there may still be outstanding issues with ipconfig).

tested the attached patch, which seems to address the issue for me at least.

live well,

    configure_networking function: Look for presence of /tmp/net-*.conf files when
    $DEVICE is not set (which is now default), otherwise ipconfig may receive a
    valid DHCP response, but fails to break out of the loop and is called
    repeatedly.
    
    Closes: #584583
