kalign: 2.03 - Switch to versioned tar ball.

Note, the previous formula had a version 2.04 set
but it was actually 2.03 (the sha1 is identical).
At least upstream told me so.

So when the real 2.04 is release, brew outdated
will falsely think this formula is up-to-date.
In this case, please:
`brew rm kalign && brew install kalign`
