[MASSEMBLY-1002] Assembly fails to include directories when they are symbolic links

Assembly fails to include directories when they are symbolic links.

E.g.

If the directory "${project.basedir}/target/surefire-reports" is a symbolic link to another directory then the following fileset will not work.

```java

${project.basedir}/target/surefire-reports
/test_results/surefire

*.*

```

However, if the directory "${project.basedir}/target/surefire-reports" is an actual directory (and not a symlinj ) and the files in that directory are symbolic links then it works as expected.

I'm guessing that this might not be a bug in this plugin but rather Maven Resources.
There is a related [issue](https://issues.apache.org/jira/browse/MRESOURCES-237) in terms of being about symlinks, but that ticket is about preserving symbolic links or not which in not the case here.

**Affects:** 3.6.0

Start by reproducing the reported fileset behavior in maven-assembly-plugin 3.6.0, using a directory path that is a symbolic link and comparing it with an actual directory containing symbolic-link files. Trace the fileset handling to determine where the linked directory is skipped. Done means files from the linked directory are included as expected.
