Code changed in jenkins

[FIXED JENKINS-7291] Permit flyweight tasks to run on master even when it has zero configured executors.
Always adding Computer for master as a fallback
The original proposed fix for
JENKINS-7291 creates a Computer object
transitively. This seems unwise as it violates the design of Computer
as stated in the javadoc, and for example we can end up creating two
Computers for the master.
I think a better fix is to create a Computer for the master all the
time, even if there's no executors configured. The discrimination in
Queue.makeBuildable would ensure that such phantom Computer is only used
as a last resort (statistically speaking).
I've also tweaked executors.jelly a bit. I simplified it somewhat
based on the idea that "if there's only one computer to show, the
context is likely making it obvious".
(I must be missing the intricacy in the current code.)
