This CL makes 'unzip' being unavailable nonfatal; instead, we just fall back to
using the old combination of directory + file pushing.

This CL also adds two gyp dependencies on chromium_commands s.t. it's built when
we're calling PushChangedFiles in b/a/gyp/push_libraries.py and in
b/a/pylib/forwarder.py.

Note that the current version of this CL is liable to cause 423025 to happen
more frequently.
