macvim: disable python support by default

MacVim currently fails to link against nixpkgs python because Xcode's
clang doesn't understand the LLVM bitcode in the
`libpython${pythonVersion}.a` static library. I'm not sure what this
static library is for when `lib/libpython${pythonVersion}.dylib` exists,
but I don't know of a way to tell MacVim to ignore it. Linking against
python works if we rebuild python to skip the static library but that
doesn't seem like a proper solution, so until a permanent solution is
found, just disable python by default.

Also mark macvim as no longer broken.
