A few tests weren't compatible with bzlmod, so would fail when it was enabled. The various causes and fixes are: * Under bzlmod, `runfiles.CurrentRepository()` returns the empty string for the main repository. To fix, an environment variable is used to tell the test whether bzlmod is enabled or not. * Accessing data files through `TEST_SRCDIR` directly is error-prone under bzlmod because the directory name within runfiles changes from the workspace name to `_main`. To fix, use the runfiles libraries, which know how to map apparent repo names to the actual directory name. In the integration tests, the runfiles library isn't available, so just check for the `_main` directory instead. Work towards bazelbuild#1469
