ext patches: Remove patches_template.ini load

Remove patches_template.ini load.
- It has useless patches, which some times, users confuse them for "bad" patches, even though they aren't.
- No one reads on how it works and it's constantly mishandled when there's no patches.ini (which completely overrides it).
- It was not supposed to be edited.

Also release will not include it anymore.
Template will still exist for demonstrating the syntax of `patches.ini`

This commit also corrects the patches.ini encoding note as ASCII.
