Re-introduce NetBSD support

[ History added by Mathieu Desnoyers:

commit bd252a04bbbb ("Use urcu/tls-compat.h")
introduce support for OpenBSD, NetBSD and Darwin by using tls-compat.h
in across urcu. (v0.7.0)

commit 9ba261bd496f ("Android: add a compat layer for 'syscall.h'")
added a syscall compatibility layer for Android. (v0.9.0)

commit b10602e3b143 ("Port: Add Solaris support to urcu/syscall-compat.h")
added Solaris support to urcu/syscall-compat.h (v0.9.0), and doing so
added a:

    #else
    #error "Add platform support to urcu/syscall-compat.h"

preventing build to succeed on unlisted platforms. Before that commit,
unlisted platforms would rely on fallback implementations for
urcu_get_thread_id() (getpid()), futex_async() (busy-wait with poll(2)
delay), and futex_noasync() (pthread_cond(3)).

The choice was made at this point to fail build on OSes that were not
tested against in order to allow consideration of better suited
implementations for urcu_get_thread_id(), futex_async(), and
futex_noasync(), and ensure a minimum level of testing.

commit 80a92637ed8c ("Add FreeBSD, DragonFly to syscall-compat.h")
re-introduce support for FreeBSD and DragonFly (v0.12.0).

commit 020351f306d4 ("Add support for OpenBSD")
re-introduced OpenBSD support implementing urcu_get_thread_id() with
getthrid() (v0.13.4).
