crash-stats.mozilla.org no longer follows symbolic links to identify module filenames

[karlt]

e.g. https://crash-stats.mozilla.org/report/index/4ffc6620-fdee-4ab2-b541-a2c140240220#tab-modules
Expected: Filename or Debug Filename libexpat.so.1.8.10.
Actual: Filename and Debug Filename both libexpat.so.1.

Version information is still kind of available in the Debug Identifier, but this requires guessing the library version, finding a library built with exactly the same compiler, options, and dependencies, and running dump_syms on the library.

Canonical full paths (/usr/lib64/libexpat.so.1.8.10) are in the .dmp files, so this appears to be a regression in their processing, though others think that is less clear. It regressed sometime before bug 1824634 comment 3.

Changes for https://bugzilla.mozilla.org/show_bug.cgi?id=1847098 may mitigate this considerably, but I wonder whether they are making some assumptions about filename formats.
