feat(linux): add device names options

[jtroo]

Implements #376, #378

[jtroo]

Note: I haven't tested the functionality by unplugging or replugging devices since I typically only use Linux via Virtual Machines or WSL2, and I don't ever attach the USB keyboard device to the VM directly. But I think it should work.

I don't see any issues with linux-dev-names-exclude

However, I think there's a problem with linux-dev-names-include:

1. I started kanata with the keyboard I want to remap specified in linux-dev-names-include
2. at 11:28:24 I plugged out the keyboard
3. at 11:28:33 I plugged in the keyboard back

Adding 200 ms sleep here no longer throws an error.

Thanks for testing!

Added a sleep, though in a different line of code, to be more targeted. A single hard-coded longer sleep feels a little unclean, as opposed to shorter retry-sleeps, but I think in practice it doesn't matter since this only happens when plugging in a new keyboard.
