Remove calf patches

[tresf]

Closes #28
Per calf-studio-gear/calf#46

Learned/cherry-picked from:

• Calf plugins for Mac OS X? calf-studio-gear/calf#72 (comment)

Testing steps:

brew untap david0/homebrew-audio
brew tap tresf/homebrew-audio
brew install --HEAD calf
ln -s $(brew --prefix calf)/lib/lv2/calf.lv2  ~/Library/Audio/Plug-Ins/LV2/calf.lv2

What works:

• Plug-Ins load and make sound

What doesn't work:

• Suil UI stuff seems to be broken, so no UI. Might be a configuration issue on my local, but x42 plugins using Qt5 Cocoa work, so I'm not entirely sure (Testing with LMMS LV2 snapshot from here Lv2 UI - Testing LMMS/lmms#7201).
