src: make process.env work with symbols for in/delete
The getter for process.env already allows symbols to be used, and in
operator as a read-only operator can do the same.
delete a[b]
operator in ES always returns true
without doing anything when b in a === false
. Allow symbols in the deleter accordingly.
