    bitbake: bitbake: main: add 2 environment variables
    
    Bitbake uses set of environment variables to set command line
    options, e.g. seeting BBTOKEN variable has the same effect
    as using --token command line option.
    
    Added new environment variables BBPRECONF and BBPOSTCONF that
    are equivalents of --read and --postread command line options.
    They can be used by high level scripts to append or prepend
    configuration files to conf/local.conf
