Eric Biggers 1af424b154 lib/crypto: poly1305: Restore dependency of arch code on !KMSAN 
Restore the dependency of the architecture-optimized Poly1305 code on
!KMSAN.  It was dropped by commit b646b782e5 ("lib/crypto: poly1305:
Consolidate into single module").

Unlike the other hash algorithms in lib/crypto/ (e.g., SHA-512), the way
the architecture-optimized Poly1305 code is integrated results in
assembly code initializing memory, for several different architectures.
Thus, it generates false positive KMSAN warnings.  These could be
suppressed with kmsan_unpoison_memory(), but it would be needed in quite
a few places.  For now let's just restore the dependency on !KMSAN.

Note: this should have been caught by running poly1305_kunit with
CONFIG_KMSAN=y, which I did.  However, due to an unrelated KMSAN bug
(https://lore.kernel.org/r/20251022030213.GA35717@sol/), KMSAN currently
isn't working reliably.  Thus, the warning wasn't noticed until later.

Fixes: b646b782e5 ("lib/crypto: poly1305: Consolidate into single module")
