Move binary search tool to toolchain-utils with a comprehensive test suite.

We now can test the binary search tool with -
  ./binary_search_tool_tester.py
This will generate a set of object files with some bad ones, and call
the binary search tool to find them out.

TEST=gpylint and passed my test suite
BUG=None
