CQ failing with: attribute lookup portage.dbapi.vartree._owners_db failed

Project Member Reported by allenwebb@google.com, Dec 21 
After the portage uprev ( crbug.com/874977 )
./build_packages --board=${BOARD} --withdebugsymbols
Is blocking the CQ with the following failure:

cros_install_debug_syms: Unhandled exception:

The following revision refers to this bug:

cros_install_debug_syms: Temporary hack to fix  crbug.com/917405 .

The portage uprev caused RunTasksInProcessPool to fail because of a
pickling error:
  attribute lookup portage.dbapi.vartree._owners_db failed
This works around the problem by keeping everything in process.

This needs to be replaced with a proper fix once the CQ stabilizes.
