netns/bpf.h gets included by netdevice.h (thru net_namespace.h) which in turn gets included in a lot of places. We should keep netns/bpf.h as light-weight as possible. bpf-netns.h seems to contain more implementation details than deserves to be included in a netns header. It needs to pull in uapi/bpf.h to get various enum types. Move enum netns_bpf_attach_type to netns/bpf.h and invert the dependency. This makes netns/bpf.h fit the mold of a struct definition header more clearly, and drops the number of objects rebuilt when uapi/bpf.h is touched from 7.7k to 1.1k.
