[metalos][oss] assorted small fixes

Summary:
* pick up metalos deps in antlir opensource generator
* fix rust macro
* use `antlir//` cell in a variety of antlir macros
* allow uids/gids to float due to lack of internal maps
* make some antlir apis (and resources for those) more publicly visible

Test Plan:
```
❯ arc skycastle run //tools/skycastle/workflows2/metalos/oss/metalos-oss-tests.sky:test_target_graph
```
