binary search tool: Add object bisecting to bisect.py

Add object file bisecting to bisect.py. This is the frontend to the
sysroot_wrapper bisection scripts. This bisection mode takes the
following arguments: board, remote IP, package to bisect, and optionally
the directory for the good/bad build trees.

Adds default install/test scripts to sysroot_wrapper (similar to
default scripts in cros_pkg) to support this bisection mode.

TEST=Run unit tests and system test with cryptohome package
