8295111: dpkg appears to have problems resolving symbolically linked native libraries

[vpa1977]

Hi all,

This pull request contains a backport of commit 32946e18 from the openjdk/jdk repository.

The commit being backported was authored by Alexey Semenyuk on 18 Apr 2024 and was reviewed by Alexander Matveev.

This change fixes an issue caused by usrmerge on Debian-based systems - dpkg -S does not return a package containing a symlinked shared library in /lib, e.g.

dpkg -S /lib/x86_64-linux-gnu/libmd.so.0
# dpkg-query: no path found matching pattern /lib/x86_64-linux-gnu/libmd.so.0

The fix calls toRealPath() to resolve an actual path to the file before dpkg call and falls back to the old behaviour if the dpkg call fails.

The change is tested by jpackage set of jtreg tests and should be low risk.

jpackage tests pass:
