Added {libc} to binary target name

refs #1576

- without this, we can't differentiate between glibc and musl Linux
  environments and Alpine download a binary linked to glibc
- other projects provide prebuilt musl binaries, so I think that's wise
  here too
- also updates README with the new target names

 The module uses [node-pre-gyp](https://github.com/mapbox/node-pre-gyp) to download the prebuilt binary for your platform, if it exists. These binaries are hosted on GitHub Releases for `sqlite3` versions above 5.0.2, and they are hosted on S3 otherwise. The following targets are currently provided:
