[install] assorted fixes & improvements (#2011)

- take `peerDependencies` into account during package placement
- do not recursively resolve `workspaces` (matches `npm`)
- link binaries to non-root packages correctly
- prune empty nodes during dependency tree construction
- support non-standard `workspace:` specifier
