Revert "package/libopenssl do not build in parallel"

This reverts commit 27ab880ebb9a3efdec15733841f7b88063604247.

With the (proposed) fix from the openssl developers added as
0004-Serialize-install-process-to-avoid-multiple-make-dep.patch, the
workaround can now be dropped so openssl can again be built and installed in
parallel, significantly speeding up builds.
