Subject: [PATCH] Deal correctly with wx directory being a symlink in docs
 generation script.

The script calling Doxygen is smart enough to strip the path of the wxWidgets
directory from the paths of the files, but it didn't do it correctly if this
directory was a symlink.

Fix this by using readlink, if available, to get the canonical name.

Closes #14796.
