cli: don't split multiple-strings flags on comma 

Looks like I used StringSliceVar (which splits on comma)
where I should have always used StringArrayVar (which does not).

Bug report contains this example of misbehavoir:

	#gocryptfs -extpass 'echo abc,123' -init testdir
	Reading password from extpass program "echo abc", arguments: ["123"]
	extpass cmd start failed: exec: "echo abc": executable file not found in $PATH

Fixes https://github.com/rfjakob/gocryptfs/issues/730
