[DebugInfo] Don't use realpath when looking up debug binary locations. Summary: Using realpath makes assumptions about build systems that do not always hold true. The debug binary referred to from the .gnu_debuglink should exist in the same directory (or in a .debug directory, etc.), but the files may only exist as symlinks to a differently named files elsewhere, and using realpath causes that lookup to fail. This was added in r189250, and this is basically a revert + regression test case.

# REQUIRES: shell
# Ensure that no realpath assumptions are made about .gnu_debuglink paths.
# Copy inputs to some other location with arbitrary names, with the original
# filenames just being symlinks to the copies. Real files go in the "real" dir,
# symlinks (with original names) go in "syms".
