Currently buildscripts/debugsymb_mapper.py expects that debug symbols is a separate *.debug file, e.g. mongod and mognod.debug. But this is not the case for sanitizer builds, where debug info is in the same binary file, e.g. mongod.
Because of that mongo-debugsymbols.tgz file that is attached to archive_dist_test_debug task doesn't contain actual debug symbols for sanitizer builds and generate_buildid_to_debug_symbols_mapping fails to find actual debug symbols files, e.g. failed task.
We should use binaries that are attached to archive_dist_test task to extract Build ID information for sanitizer builds.
