process-attributes-ps-args / process-attributes-ps-format for Darwin

[Filipp Gunbin]

Hello Michael,

Here's the patch for Darwin.

Also I've added a piece of code to automatically set profile for local
sudo case, so the users on macOS don't see the empty list in Proced by
default.

Strangely, ps on macOS doesn't have keyword to output group name, so
I've omitted it.

Thanks,
Filipp
