commit d9e4d43f37814a1e0752ec2b6bae2882b69fa569

portable: improve panelw detection

Rather than making certain checks for panelw dependant on the underlying
operating system, actually use pkg-config's detection mechanism
properly.

This makes the checking for panelw much easier and broader for other
OSes which might have either panelw or gnupanelw.
