This lets us remove the unmaintained StackWalker library and its hacky
upstream_utils script.
@Gold856 reported that StackWalker gives blank stacktraces:

They also reported an earlier version of this PR giving the following
stacktrace instead:

This follows the gradle build accurately. Gradle copies debug symbols
into a second file (libfoo.so.debug) and links it back into the .so
file. Disable this behavior when gradle doesn't do it today.
Also, name everything correctly. When building debug builds, most
libraries get a 'd' at the end of them. Do that here too.
