This extends the calling convention for nint in a non-breaking way: If
the called script returns an attribute set instead of a string the
following is done:
* If the attributes `stdout` and/or `stderr` exist, their content (which
must be a string currently) is written to the respective output.
* If the attribute `exit` exists, nint will exit with the given exit
code. Must be a number that can be converted to an `i32`. If it's
missing, nint will exit without indicating an error.

Since //web/bubblegum depends on nint, we need to move it to a non user
directory to conform with the policy established via cl/3434.
Note that this likely doesn't mean greater stability (which isn't
really implied in depot anyways), since I still would like to use a more
elaborate calling convention to allow for additional useful features.
