vim @8.2.2681+huge: Removing libcanberra breaks vim

[evanmiller (Evan Miller)]

Per ​https://github.com/vim/vim/issues/4531, libcanberra is linked into vim during a +huge build. However, this is not indicated in the Portfile, so removing libcanberra results in a broken vim.

$ /opt/local/bin/vim
dyld: Library not loaded: /opt/local/lib/libcanberra.0.dylib
  Referenced from: /opt/local/bin/vim
  Reason: image not found

I suggest passing in --disable-libcanberra or else declaring it as an explicit dependency.
