llvmpipe: do not enable tessellation shader without llvm coroutines support

Browse Source 
Tessellation shader in llvmpipe depends on llvm coroutines support. So do not
advertise tessellation shader support in llvmpipe if GALLIVM_HAVE_CORO is FALSE.

This fixes assertion in LLVMTokenTypeInContext() running tessellation shader
tests with llvm version < 6.

Fixes: eb522717 "llvmpipe: add support for tessellation shaders"
