    bitbake: utils: Force bitbake to en_US.UTF-8 locale setting everywhere
    
    Under python 3, if we spawn python processes, we need to have a UTF-8
    locale, else python's file access methods will use ascii. You can't
    change that mode once the interpreter is started so we have to ensure
    a locale is set. Ideally we'd use C.UTF-8 since OE already forces the
    C locale but not all distros support that and we need to set something.
    Was tempted to choose en_GB so colour gets spelt correctly :).
    
    This is in some ways pretty nasty, forcing it into the environment
    everywhere however we only have a limited number of ways of making
    everything work correctly and this beats having to add utf-8 encoding
    to every file access command.
    
    A similar change will be needed to bitbake.conf in OE.
