os,tools: add os.vtmp_dir()

Browse Source 
Use it to consistently place all temporary files created by tests in a overridable folder specific to the user, that is easy to cleanup later.

NOTE: os.temp_dir() on macos returns `/tmp`, and using `/tmp/v` is a problem when multiple unix users are trying to access/create/write to it.
