The ip_fast_csum and csum_ipv6_magic tests did not work on all
architectures due to differences in endianness and misaligned access
support. Fix those issues by changing endianness of data and aligning
the data.

on the v4, but looks like it got lost. I'm happy to take this via the
RISC-V tree, as that's how I merged the broken patches in the first
place, but no big deal if someone else wants to pick it up.
It looks like the issues are all resolved and such, but there's been a
long tail of them so I'm not 100% sure here...
