Bug#717805: initramfs-tools: lsinitramfs doesn't understand early microcode images

[Stephen Powell <zlinuxman@wowway.com>]

Brett, your patch (and Olivier, your revised one) don't seem to work for me
anymore.  By trial and error experimentation (wild guessing), I find that
the "magic number" is no longer 8, but 4, for the two initial RAM file systems
that I currently possess, both of which have a real_offset value, before
incrementing, of 6796.  I note that 6796 divided by 8 yields a quotient of 849
and a remainder of 4.  Hmm.  Adding 4 brings the value to an integer multiple
of 8.  I wonder.  Maybe the correct algorithm is

   real_offset=$(((real_offset+8)/8*8))

This will bump real_offset to the next higher multiple of 8.  Is this correct?
I have no idea.  What I do know is that the current algorithm doesn't work for
me, but the above does.  For now.  Will it continue to work in the future?
I don't know.
