Extend YAML::Syck::DefaultKey fixing to marshal_dump as well.

[danp]

I'm running into a problem on our internal gems repo where built-gem
metadata is being uploaded with unquoted ='s. When gem generate_index is run, the metadata is loaded which turns the
= into DefaultKey. That's then marshaled out as part of the quick
specs which breaks clients that try to load them.

Applying the same fix to marshal_dump let quick specs be generated
that didn't have DefaultKey refs in them even though the incoming
gem specs were broken.

On a test version of a gem built on Win7 32bit with RG 1.8.8 and installed with RG 1.8.9 I'm seeing an install failure that appears similar to this issue. The failure only occurs for me on MRI 1.8.7; MRI 1.9.3dev and 1.9.4dev are OK.

Can anyone reproduce?

@jonforums: seems the issue associated with the generated gemspec. Can you verify the contents of the generated .gem and see inside metadata both all dependencies state YAML::Syck::DefaultKey:0x3b61f18 ?

I can reproduce with a checkout of https://github.com/rtomayko/posix-spawn.git by rake19 package; gem install pkg/posix-spawn-0.3.6 rake19 is 1.9.3, gem is 1.8.7
