net: fastboot: make UDP port net: configurable

The fastboot protocol uses per default the UDP port 5554. In some cases
it might be needed to change the used port. The fastboot utility provides
a way to specifiy an other port number to use already.

  fastboot -s udp:192.168.1.76:1234 boot fastboot.img
