bisect-kit: handle git repo merging
src/buildtools moved into src/, changes in bisect-kit needed
1. We cannot simply rmtree src/buildtools because its children are
moved to src/ as well. This CL handles by removing and adding all
its children repos.
2. Because of above removing and adding, we need to runhook again.
This CL do runhook for every switch. This is more correct behavior
with cost about half minutes per switch.
BUG=chromium:930047,b:126633034
TEST=switch_cros_cr_localbuild_internal.py works well between 74.0.3690.0 and 74.0.3700.0
