Make hermetic interpreters compatible to disallow_empty_glob (#761)
Make hermetic interpreters compatible to disallow_empty_glob (#761)

A single filegroup is used to aggregate the interpreter files.
Its platform specific regex patterns are not compatible to the flag
`--incompatible_disallow_empty_glob` which forbids any pattern to return
an empty list. For example, on a Linux host the `"*.exe",` will be empty.
