Subject: [SCons] Fix caching and path detection.

Add version file depenencies to SSL and RTC targets.

Disable OpenSSL caching since it causes issues as it doesn't properly
cache generated header files.

Add hack to prepend PATH and few other vars (should probably be added
to upstream godot-cpp), and clone scons envs when building ssl/rtc (so
that PATHs are properly setup).
