Fix the following build failure with kernel >= 6.7:

/home/buildroot/autobuild/instance-0/output-1/build/cryptodev-linux-1.13/./cryptlib.c: In function ‘cryptodev_hash_init’:
/home/buildroot/autobuild/instance-0/output-1/build/cryptodev-linux-1.13/./cryptlib.c:384:28: error: implicit declaration of function ‘crypto_ahash_alignmask’; did you mean ‘crypto_aead_alignmask’? [-Werror=implicit-function-declaration]

+Subject: [PATCH] Fix build for Linux 6.7-rc1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since Linux 6.7-rc1, no ahash algorithms set a nonzero alignmask,
+and therefore `crypto_ahash_alignmask` has been removed.
+
+See also: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0f8660c82b79af595b056f6b9f4f227edeb88574
