    Remove flex/bison dependencies.
    
    configure says "You need bison to build evolution-data-server"
    
    No, actually, you don't.  In fact I have no idea why these were ever
    needed.  "git blame" shows the requirements were present even in the
    initial evolution-data-server commit in 2003, and yet even back then
    I can't find evidence that flex or bison were actually used.
