package/libopenssl: fix build on x86

In some specific configurations (target 32bit x86, disable compiler
optimizations, and openssl binary enabled), the compilation fails
with the error:

/home/autobuild/autobuild/instance-7/output-1/host/lib/gcc/i686-buildroot-linux-gnu/14.3.0/../../../../i686-buildroot-linux-gnu/bin/ld: ./libcrypto.so: undefined reference to `ossl_aes_cfb128_vaes_dec'
/home/autobuild/autobuild/instance-7/output-1/host/lib/gcc/i686-buildroot-linux-gnu/14.3.0/../../../../i686-buildroot-linux-gnu/bin/ld: ./libcrypto.so: undefined reference to `ossl_aes_cfb128_vaes_enc'

The issue can be reproduced with the commands:

    cat >.config <<EOF
    BR2_x86_corei7=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_OPTIMIZE_0=y
    BR2_PACKAGE_OPENSSL=y
    BR2_PACKAGE_LIBOPENSSL_BIN=y
    EOF
    make olddefconfig
    make libopenssl

This commit adds a patch to fix the issue.

+Subject: [PATCH] Scope aes_cfb128_vaes_encdec_wrapper to x64
+
+This function is only used on x64 and relies on other functions which
+are only implemented for x64.
+Fixes #28745.
