This enables an engine during its package's installation, by adding it
to the engines list in /etc/ssl/engines.cnf.d/engines.cnf.
The engine build system was reworked, with the addition of an engine.mk
file that groups some of the engine packages' definitions, and could be
used by out of tree engines as well.

This changes the configuration of engines from the global openssl.cnf to
files in the /etc/ssl/engines.cnf.d directory. The engines.cnf file has
the list of enabled engines, while each engine has its own configuration
file installed under /etc/ssl/engines.cnf.d.
Patches were refreshed with --zero-commit.
