mmap_unix.go missing BSD in Go build tag

[vendion]

https://github.com/bytedance/sonic/blob/8c71eb047516a6b70f216887923f353f42d0501b/loader/mmap_unix.go#L1C1-L2C23

Would it be possible to make the loader/mmap_unix.go file target more Unix based OSes than just Darwin and Linux? I'm trying to build a project that indirectly depends on this package and I get the following build error.

# github.com/bytedance/sonic/loader
../../go/pkg/mod/github.com/bytedance/sonic@v1.10.2/loader/funcdata_latest.go:228:13: undefined: mmap
../../go/pkg/mod/github.com/bytedance/sonic@v1.10.2/loader/funcdata_latest.go:233:5: undefined: mprotect

didn't try before. Are you interested in giving a PR?

Well it is a very simple change as the syscalls for the BSDs should match those for Darwin (based on BSD anyways) & Linux so something like this should be more than enough:

Unless you have reasons for being explict in this case.

I didn't submit a PR, as it's a one line change and that the formatting of the file doesn't follow the standard gofmt standard so the whole flie would end up being needlessly modified.

ok，I will submit it
