The Lua headers are needed because, yes, NetBSD has a kernel module for Lua support. soundcard.h is technically a system header but is installed by libossaudio and so was missed previously. This also removes some riscv headers that shouldn't have been added because NetBSD does not yet officially support the riscv32/riscv64 ports. Closes #24737.
