  1. login: Fix empty input prompt 

    Issue rustwasm#484.

PR392 inadvertantly replaced the `login` interactive process spawner
with
`child::run`, which is hard-coded to buffer stdout/stderr. This caused
`login` to become essentially unusable; the user could no longer see
interactive input prompts or error messages displayed by `npm adduser`.

The code was not directly reverted because the previous version:
1. Returned Error instead of failure::Error. (Updated to use
`bail!`, which is consistent with `publish`.)
2. Displayed all stderr only upon exit, rather than interactively
displaying it. This led to repeated interactive prompts without
informing the user why. (Updated to use `status()` which inherits
stdin/stdout/stderr by default.)
3. Did not provide logging. (Now duplicates the logging in
`child::run`.)

  2. login: Send arguments separately to npm 

    All arguments were passed to `arg` inside one string when building a
`Command`. However, using the `arg` function, "only one argument can be
passed per use." This caused all arguments accidentally to be appended
to the registry URL. For example: After a successful login with a
provided `--auth_type`, the success message incorrectly displayed:
"Logged in as asf on https://registry.npmjs.org/%20--auth_type=Basic."
The space (%20 in hex) was caused by adding a fixed space before each
additional argument.

This commit pushes all arguments onto a `Vec<String>`. Then, the `args`
function adds the arguments separately to the command. This removes the
need to prepend spaces to each argument. Alternatively, `arg` could have
been used throughout to build the command argument-by-argument. However,
using `args` partitions the code more neatly into two distinct sections.
