Revert r58345 and r58371.
These changes break the behavior of default gems. Bug #13428 says
r58345 is reasonable because gemspec file is installed by `to_ruby_for_cache`
method. But I revert `to_ruby_for_cache` in rbinstall.rb at r58403.
There is no reason that we apply r58345 now.
But I'm not sure about gemspec of default gems affects standalone gems.
I'm going to investigate it on rubygems/rubygems.
