[NFCI] Move Keccak rhotates tables to rodata

rhotates tables are placed to .text section which confuses tools such as
BOLT. Move them to rodata to unbreak and avoid polluting icache/iTLB
with data.

1. Update patch file using the steps in scripts/copy_from_xkcp/README
2. Apply the updated patch with scripts/copy_from_xkcp/package.sh

Sync with XKCP upstream: https://github.com/XKCP/XKCP/pull/137
Similar fix in OpenSSL: https://github.com/openssl/openssl/pull/21440
Redo of https://github.com/open-quantum-safe/liboqs/pull/1508
