gemini: Use library functions to assign MAC address

This simplifies the ethernet address extraction script
by using standard library functions to locate the MTD
partitions and extract ethernet address from a binary
offset location in the flash. Furthermore, the aging
ifconfig is replaced by the ip tool, which will now
assign the MAC addresses.

[ifconfig replacement, use -n instead of ! -z,
-n requires string to be quoted within the test brackets,
drop prepended "x" in check, add quotes, make local
variables local, kill whitespaces]
