Where to look for itch, when not the current user on the current machine.
Every field defaults to the ambient value, so passing nothing searches for
the running user's own installation. Supplying them lets a caller ask where
itch would be for another home directory, environment or operating system
-- useful for tools that scan several user profiles or inspect a mounted
disk, and the reason this library's own tests never have to mutate
process.env.
