package/libopenssl: fix powerpc64 build

Buildroot commit f710640be5 bumped the
package to version 3.6.0 that includes upstream commit
8f24a148e6
which causes build errors on powerpc64.

The upstream commit was also backported to older libopenssl branches:
https://github.com/openssl/openssl/pull/28990#issuecomment-3675219918
but its first appearance on the buildroot master branch was with said
bump to 3.6.0.

This patch adds an upstream patch to fix the problem.
