Subject: [PATCH] libgcrypt.c: Fix prototype of des3_encrypt/des3_decrypt

This is to match the prototype for callback functions which are now emitted as
errors by clang16

Fixes

TOPDIR/build/tmp/work/cortexa15t2hf-neon-yoe-linux-gnueabi/libssh/0.10.4-r0/git/src/libgcrypt.c:903:20: error: incompatible function pointer types initializing 'void (*)(struct ssh_cipher_struct *, void *, void *, size_t)' (aka 'void (*)(struct ssh_cipher_struct *, void *, void *, unsigned int)') with an expression of type 'void (struct ssh_cipher_struct *, void *, void *, unsigned long)' [-Wincompatible-function-pointer-types]
    .encrypt     = des3_encrypt,
                   ^~~~~~~~~~~~
