Summary: I'm pretty sure that `@group` annotations are useless now... I believe that they were originally used by Diviner?

Test Plan: Eye-balled it.

Minor change to `ArcanistPhutilLibraryLinter`

Summary: Ref T5577. Modify `ArcanistPhutilLibraryLinter` to use `PhutilLibraryMapBuilder` instead of using an `ExecFuture` to run `phutil_rebuild_map.php`.

Test Plan: Ran `arc lint`.

Decrease the priority of the `ArcanistPhutilLibraryLinter`

Summary: Ref T5577. Decrease the priority of the `ArcanistPhutilLibraryLinter` such that it is lower than that of the `ArcanistXHPASTLinter`. There isn't any specific reason that we should do this, although it seems to generally be a reasonable idea.

Test Plan: N/A

Don't build unused linters for the `ArcanistConfigurationDrivenLintEngine`

Summary: Fixes T5124.

Test Plan: `arc lint` on a Phabricator diff that doesn't have JS files doesn't complain on missing JSHint.

Allow the `ArcanistPhutilLibraryLinter` to recover from PHP syntax errors

Summary: Fixes T5577. If the `ArcanistPhutilLibraryLinter` lints a PHP file that contains a syntax error, it will die horribly. Instead, force it to continue as if nothing was wrong.

Test Plan: Introduced a PHP syntax error. Ran `arc lint` and made sure the output looked reasonable.

Parameterize `@{upstream}` in arc to fix Windows

Summary: We manually quote this in a couple of places. That works fine on Lunix, but does not work on Windows. Instead, explicitly parameterize the command so the correct quoting rules are applied for the OS.

Test Plan: See IRC; windows user had issues fixed by this. `arc:upstream` still works locally.
