Hsuan-Chi Kuo 561d13128b seccomp: Fix setting loaded filter count during TSYNC
commit b4d8a58f8dcfcc890f296696cadb76e77be44b5f upstream.

The desired behavior is to set the caller's filter count to thread's.
This value is reported via /proc, so this fixes the inaccurate count
exposed to userspace; it is not used for reference counting, etc.
