Subject: bitbake: cooker: Fix main loop starvation when parsing

When parsing, the parser isn't servicing the main loop so a Ctrl+C in the
UI won't be seen on the cooker/server side. Fix this by returning when queue
timeouts occur. This helps where there is a hung or slow parsing thread.

(Bitbake rev: a2cde38311a51112dca5e7bb4e7feaf4e6a281b3)
