Bug: Bizhawk is given garbled connector script path on Linux

[Firepal]

What happened?

When trying out the Mega Man 2 integration I hit a bug where Bizhawk was told to run a script from a nonexistent path Z:\tmp\.mount_ArchipdMkAdm\opt\Archipelago\tmp\.mount_ArchipdMkAdm\opt\Archipelago\data\lua\connector_bizhawk_generic.lua; notice the path repetition. I had to remove the script and drag'n'drop it from where the temporary folder actually was, and the integration otherwise works.

What were the expected results?

The connector script path in Bizhawk should've been Z:\tmp\.mount_ArchipdMkAdm\opt\Archipelago\data\lua\connector_bizhawk_generic.lua

I believe the offending line is in here

Archipelago/worlds/_bizhawk/context.py

Lines 310 to 322 in aa3614a

	if auto_start is True:
	emuhawk_path = settings.get_settings().bizhawkclient_options.emuhawk_path
	subprocess.Popen(
	[
	emuhawk_path,
	f"--lua={Utils.local_path('data', 'lua', 'connector_bizhawk_generic.lua')}",
	os.path.realpath(rom),
	],
	cwd=Utils.local_path("."),
	stdin=subprocess.DEVNULL,
	stdout=subprocess.DEVNULL,
	stderr=subprocess.DEVNULL,
	)

By the way I am using the latest AppImage version

I assume *path here passes each element of ['data', 'lua', etc] as individual args?

The only possibility I see here is that, at some point before emuhawk is called, cached_path is set to "\tmp.mount_ArchipdMkAdm\opt\Archipelago\tmp.mount_ArchipdMkAdm\opt\Archipelago" somehow

Edit: Actually that can only happen in this function, since cached_path is only ever set here
