what do you think about making a new chrome path for this? we already have
DIR_CRASH_DUMPS, so why not DIR_KASKO or somesuch? you could then perhaps use
GetDefaultUserDataDirectory in some way.

my reason for suggesting this is that i think it's better to have the sort of
logic you have here consolidated either in a path provider somewhere or in the
installer somewhere.
