python3: Fix hashlib module not compiled for host Python

026-openssl-feature-flags.patch and
028-host-python-support-ssl-with-libressl.patch were removed in
4ecd9d67e90651a8e93760bf0b5771f7057c74a8 to fix the ssl module after
libressl was upgraded to 3.7.0[1].

However, the cause of the ssl module build failure was only
028-host-python-support-ssl-with-libressl.patch.

Removing 026-openssl-feature-flags.patch caused a build failure for the
hashlib module.

This restores 026-openssl-feature-flags.patch with an updated version of
the patch from OpenBSD[2].
