runtime: initialise cpu.HWCap on netbsd/arm64
NetBSD does not supply AT_HWCAP, however we still need to initialise
cpu.HWCaps. For now specify the bare minimum until we add some form of
capabilities detection. See
https://golang.org/issue/30824#issuecomment-494901591
Follows CL 174129 which did the same for openbsd/arm64.
Updates #30824
