luci-base: fix parsing of ethers(5)

The /etc/ethers file may contain any number of white space characters
between the mac address and the IP/hostname field, so extend the pattern
to allow for that.

Man ethers(5) also states that the IP field may be a symbolic hostname,
so test whether the name is an IP address or hostname before adding it
to the hints structure.

Fixes #1674.
