    tools/firmware: reproducible seabios build
    
    The build system of seabios always includes the current time and the
    hostname into the resulting binary. To avoid that, it is required to
    have a file '.version' in the toplevel directory of seabios-dir-remote.
    And it is required to pass EXTRAVERSION= to make because its toplevel
    Makefile does not take EXTRAVERSION from environment.
    
    Adjust the code to create a '.version' file with fixed content.
    Adjust the code to pass EXTRAVERSION down to make.
