Remove the obsolete needle dependency

The `needle` dependency originally got introduced in mozilla#12024, almost four
years ago, to be able to use pre-built binaries for the `canvas`
dependency on macOS. However, nowadays the `needle` dependency isn't
used by `canvas` anymore, or any other package we use for that matter,
as shown by the empty NPM dependency tree:

```
$ npm ls needle
pdf.js
└── [email protected]
```

Investigation showed that the `canvas` package depends on the
`node-pre-gyp` package which in turn depended on `needle` (see
Automattic/node-canvas#1110 (comment)),
but in version 1.0.0 of `node-pre-gyp` from three years ago the `needle`
dependency got dropped in favor of `node-fetch`. This explains why the
NPM dependency tree is empty now and proves that we can safely get rid
of this dependency.
