Subject: Always generate non-empty revision.h

Non-GNU make seems to generate empty revision.h, but it doesn't make
sense since https://github.com/ruby/ruby/pull/6382.

Also the $(HAVE_BASERUBY:yes=tmp) hack doesn't seem to be working on
OpenBSD. I'll remove it to focus on fixing RubyCI first, and then deal
with baseruby-missing environments. At least a snapshot should have
revision.h and it might work fine though.
