make-bcache: remove reduncant code

Now we have main program 'bcache', the redundant code in 'make-bcache'
can be replaced by a simple calling to make_bcache().

The reason we still have 'make-bcache' in bcache-tools is to provide
legacy compatibility for other utilities who don't start to use main
program 'bcache' yet.
