`glob` is unable to exclude recursive symlinks from evaluation

Description of the problem / feature request:

glob throws an evaluation error when it detects an infinite recursion in a directory traversal. However, it detects this recursion even if the specific subpath leading to that recursion is excluded via the exclude=[] argument.

This means that recursive symlinks cannot be ignored in glob expressions, even if they occur in subtrees that bazel does not need to be evaluating.

It may also suggest that unnecessary directory tree evaluation is being performed when using glob expressions.

Consider the following structure:

.
├── BUILD.bazel
├── foo
│   ├── bar -> ../
│   └── payload.txt
└── WORKSPACE

The following glob expression will fail to evaluate, even though several wildcards are provided to exclude=[] indicating that the foo/bar symlink doesn't need to be followed.

filegroup(
    name = "broken",
    srcs = glob(
        include = ["**"],
        exclude = [
            "foo/bar",
            "foo/bar*",
            "foo/bar/**",
        ],
    ),
)
