Golang x/sys/unix: TestMremapPtr fails with "MremapPtr: cannot allocate memory" on GOOS=netbsd

This functionality and test was recently added in CL 592415. It fails on GOOS=netbsd specifically:

=== RUN   TestMremapPtr
    mremap_test.go:67: MremapPtr: cannot allocate memory
--- FAIL: TestMremapPtr (0.00s)

(From https://ci.chromium.org/b/8744162608784922945.)

Oh. Sorry about that. I had asked to run CI tests because I couldn't test other OSes. I'll try to set up something NetBSD to test this.

I've tried to verify this fix by setting up NetBSD with GitHub actions, but would appreciate that the CL would go through this testing somehow during review?

@ncruces See https://go.dev/wiki/SlowBots. In particular, you should be able to include a footer like this:

Cq-Include-Trybots: luci.golang.try:x_sys-gotip-netbsd-arm64

That'll cause those builders to run when a Commit-Queue+1 vote is left.

Apparently there was a CI availability issue. If anyone can try again. Otherwise I'm reasonably confident due to reproducing and fixing on my end. I'll have a stab at #68181.
