update_engine: Use libchromeos to launch subprocesses.

The Subprocess class handles the execution of suprocesses in the
update_engine such as the post-install script and bspatch operations.

This patch migrates this class from using glib functions to use
libchromeos classes with equivalent functionality.

Callsites and unittests were updated to match the new interface.

BUG=chromium:499886
TEST=Unittest still pass. Deployed on link and cros flash another image
using a delta payload.
