Update build script with latest support GOOS+GOARCH combinations

GOOS+GOARCH combinations are from:

    go tool dist list

With the manual removal of linux-riscv64, as that doesn't compile
Dio properly yet:

    # golang.org/x/sys/unix
    ../vendor/golang.org/x/sys/unix/syscall_linux_gc.go:10:6: missing function body
    ../vendor/golang.org/x/sys/unix/syscall_linux_gc.go:14:6: missing function body
