Move bzip.h to payload_generator.
The in-memory bzip compression and decompression functions are only
used during payload generation and testing. This patch moves those
functions to the payload_generator/ directory and keeps the streamed
version (bzip_extent_writter.h) in the update_engine daemon.
Bug: None
Test: FEATURES=test emerge-link update_engine; `mm` on Brillo.
