[jdk15u-dev] RFR: 8272167: AbsPathsInImage.java should skip *.dSYM directories

[Sergey Bylokhov]

Hi all,
This pull request contains a backport of commit [dd93c6e2](https://github.com/openjdk/jdk/commit/dd93c6e27b66acebb221583fd28d03c65bfc1f24) from the [openjdk/jdk](https://git.openjdk.java.net/jdk) repository.
The commit being backported was authored by Sergey Bylokhov on 12 Oct 2021 and was reviewed by Magnus Ihse Bursie and Erik Joelsson.

The change is not "clean" because I have to restore the "import" which is still used by the version of the test in jdk15.

Thanks!
