.HaskellCompile.pb: openBinaryFile: does not exist

`hrepl` attempts to build the `haskell_compile_info` output group of non-Haskell targets even if they are not explicitly listed on the command-line.

This issue can be reproduced on the [`daml` repository](https://github.com/digital-asset/daml.git) as follows:
```
$ hrepl //compiler/damlc:damlc-bootstrap //compiler/damlc/stable-packages:generate-stable-package
hrepl: /home/aj/.cache/bazel/_bazel_aj/f6afc9f2c21b16cf433d30b51afb8d67/execroot/com_github_digital_asset_daml/bazel-out/k8-opt/bin/compiler/damlc/stable-packages/gen-stable-packages.HaskellCompile.pb: openBinaryFile: does not exist (No such file or directory)
```
Both targets that are specified on the command line are `haskell_binary` targets. The failing target `//compiler/damlc/stable-packages:gen-stable-packages` is a `genrule` target.

Setting the `--show-commands` flag shows that that target first appears after the first `allpaths` query:

```
Indeed, `//compiler/damlc:damlc-bootstrap` has a `data` dependency on `//compiler/damlc/stable-packages` which is a `filegroup` capturing the outputs of the `genrule` `//compiler/damlc/stable-packages:gen-stable-packages` which in turn has a `tools` dependency on `//compiler/damlc/stable-packages:generate-stable-package`.

One could argue that it doesn't make sense to try and load both those binaries into one GHCi session. Unfortunately, that doesn't prevent this issue as both `haskell_binary` targets share common library dependencies. E.g. the following will trigger the same issue
```
$ hrepl //compiler/damlc:damlc-bootstrap //compiler/damlc/daml-lf-conversion
```
where `//compiler/damlc/daml-lf-conversion` is a `haskell_library` target.

Unfortunately, I'm not aware of a `cquery` command to filter out targets that don't provide a certain output group. However, one possible way to avoid this issue would be to filter for Haskell rules before attempting to build the output groups. E.g. `kind("haskell_binary|haskell_library|haskell_test", ...)` for `compile_info` and `kind("haskell_library|haskell_cabal_library", ...)` for `library_info`. This would potentially also allow users to pass wildcards to `hrepl`, e.g.
```
$ hrepl //compiler/damlc/...
```
