Subject: RubyGems: Fix build info file location

Gem::Specification#build_info_file didn't respect the :install_dir
option and saved the build info file into a wrong lovation during gem
installation. This caused permission problems when installing gems using
Bundler, making it pretty much useless.

This fix is a backport from upstream:

  https://github.com/rubygems/rubygems/commit/26f8ed4aa7f1ac965aec8f5721ec97e84eca6043

The upstream fix is already included in RubyGems 2.0.4.
