bitbake: bitbake: Set process names to be meaninful

This means that when you view the process tree, the processes
have meaningful names, aiding debugging:

$ pstree -p 30021
bash(30021)───KnottyUI(115579)───Cooker(115590)─┬─PRServ(115592)───{PRServ Handler}(115593)
                                                ├─Worker(115630)───bash:sleep(115631)───run.do_sleep.11(115633)───sleep(115634)
                                                └─{ProcessEQueue}(115591)

$ pstree -p 30021
bash(30021)───KnottyUI(117319)───Cooker(117330)─┬─Cooker(117335)
                                                ├─PRServ(117332)───{PRServ Handler}(117333)
                                                ├─Parser-1:2(117336)
                                                └─{ProcessEQueue}(117331)

Applies to parse threads, PR Server, cooker, the workers and execution
threads, working within the 16 character limit as best we can.

Needed to tweak the bitbake-worker magic values to tell the
workers apart.
