Update to new snapshot version. We also make IPV6 optional, and
conditionally selecting the udptunnel6 module, using the same trick that
the strongswan package also uses for this kind of dependency expression.

This should massively improve performance for (at least) MIPS targets:

    * poly1305: optimize unaligned access

    This is a very appreciated fix from René van Dorst, adjusting the
    arithmetic in Poly1305 to work fast on platforms with slow unaligned
    access, such as MIPS. According to his calculation, this gives a 50%
    improvement on small MIPS boxes.

Also fix a new compilation error, due to upstream changes in the build
system.  SUBDIRS= is deprecated when building external kernel modules, use
M= instead to fix compilation.

Also add the SHA256 checksum, since upstream now publishes it when releasing:
