wine fails to start with seccomp updates for v5.9-rc1

[Alex Xu (Hello71)]

Hi,

On Linus' master, wine fails to start with the following error:

wine client error:0: write: Bad file descriptor

This issue is not present on 5.8. It appears to be caused by failure to 
write to a pipe FD received via SCM_RIGHTS. Therefore, I tried reverting 
9ecc6ea491f0, which resolved the issue.

Thanks,
Alex.
