The non-configurable node-pre-gyp's binary remote_path prevents from using bcrypt 1.0.3-3.0.0 off an enterprise artifactory

[ilatypov]

• What went wrong?
  Attempts to install bcrypt's pre-built binary from a local artifactory failed due to ignoring the subpath /artifactory/node-pre-gyp-binaries.
  npm install bcrypt@"^1.0.3" --bcrypt_lib_binary_host_mirror=https://INTERNAL_HOST/artifactory/node-pre-gyp-binaries

• What did you expect to happen?
  The host mirror variable substitutes both the host name and the beginning of the path.

• Which version of nodejs and OS?
  nodejs 8.9.4, Windows 7

[ilatypov]

Not starting "binary": { "remote_path": ... } with a forward slash works around erasing the subpath of the host mirror value due to using a url.resolve call in node-pre-gyp,

This is accidentally worked around for bcrypt releases past 3.0.0.

This is something I never took into consideration
