Title: Remove non exist files from gemspec

This commit addresses following errors at rails4 branch.

```ruby
Using activerecord-oracle_enhanced-adapter (1.4.1) from git://github.com/rsim/oracle-enhanced.git (at rails4)
activerecord-oracle_enhanced-adapter at did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
["lib/active_record/connection_adapters/oracle_enhanced_activerecord_patches.rb", "lib/active_record/connection_adapters/oracle_enhanced_base_ext.rb", "lib/active_record/connection_adapters/oracle_enhanced_tasks.rb"] are not files
```
