Remove unused/unusable relocation packer files.

Removes:
- src/run_length_encoder.h
    artifact of the original packing tool, not used here
- test_data/generate_elf_file_unittest_relocs.sh
- test_data/generate_elf_file_unittest_relocs.py
    test data generation for chromium/gyp, not usable here
- README.TXT
    because it is now almost entirely outdated
