Subject: [PATCH] patch: delete legacy code

SoftwareSpec#add_legacy_patches and Patch#normalize_legacy_patches
were added almost 6 years ago; let's delete them

See commit 665b14c4a44c272b46b8559836e9fdbeee5d8a46

```
$ grep -r 'normalize_legacy_patches' Library/Homebrew
./software_spec.rb:    list = Patch.normalize_legacy_patches(list)
./patch.rb:  def self.normalize_legacy_patches(list)
```

```
$ grep -r 'add_legacy_patches' Library/Homebrew
./software_spec.rb:  def add_legacy_patches(list)
```
