[zorg] Don't exclude compiler-rt runtimes from build.py artifacts

[vsk]

Summary

build.py tars up the cmake build products to create an artifact, but it excludes all .a files. That means that the resulting compiler artifacts aren't prepped with any compiler-rt runtimes.

Be more selective about the .a files we exclude.
