Use ninja to speed up build (#5088)
Deepspeed have too many ops now, and it take too many time to pre-build
all ops.
I notice deepspeed disabled `ninja` 4 years ago
(https://github.com/microsoft/DeepSpeed/pull/298) and I think we should
consider enable it now.
The issue mentioned in https://github.com/microsoft/DeepSpeed/pull/298
can be solved by resolving `include_dirs` to absolute path.
