This script will
1. Read the ~/.fuchsia/debug/symbol-index to load the symbol lookup paths.
2. Extract build ids from *.in files under the same directory.
3. For each build id, locate the symbol file and copy it to //prebuilt/test_data/symbolizer/symbols.
To make it simpler, this script takes no argument, supports only build_id directories and hard-codes
all paths.
