Fix ethernet icon for systems with multiple NICs wherein cat /sys/class/net/e*/operstate outputs multiple lines. Icon now shows connected when one or more NICs are connected.

This does not work if 2 NICs are "up" and grep return both, and then both "up" gets compared to a single "up" and return false as if it was down.
You can try the following for proof:

$ [ "$(echo -e "up\nup" | grep "up")" = 'up' ] && echo "🌐" || echo "❎"
❎

This would be better instead:

cat /sys/class/net/e*/operstate 2>/dev/null | grep -q "up" && ethericon="🌐" || ethericon="❎"

If grep finds at least one instance of "up" it will return a "0" (no errors) return code and "🌐" will be put in the variable.
-q tells grep to be quiet, just like piping to /dev/null but better.
If grep does not find at least one instance of "up" it will return "1" (errors) return code and "❎" will be put in the variable.

You can try the following for proof:

$ echo -e "up\nup" | grep -q "up" && echo "🌐" || echo "❎"
🌐
$ echo -e "up\ndown" | grep -q "up" && echo "🌐" || echo "❎"
🌐
$ echo "down" | grep -q "up" && echo "🌐" || echo "❎"
❎

Thanks for pointing that out. This is why I rarely open PRs.

Small suggestion, you can change

cat /sys/class/net/e*/operstate 2>/dev/null | grep -q "up" /sys/class/net/e*/operstate && ethericon="🌐" || ethericon="❎"

to:

grep -q -m1 'up' /sys/class/net/e*/operstate && ethericon="🌐" || ethericon="❎"

It's slightly faster because cat is not needed anymore, and the -m1 option makes grep instantly stop after it has found its first match.
