[PATCH 2/3] lib: crc32: mark test data __initconst

[George Spelvin]

So it gets discarded after the selftest.

This is the patch I started with, when I was looking for lib/ self-test
code to emulate for my still-pending glob.c code.  But curiosity about
the combine code led me notice problems with it, and to study the
arch/x86/crypto code, where I also have a proposed patch.

Aren't tangents fun?
