This patch allows fcntl with F_SETFL and no filters.

The fcntl function with F_SETFL is called from various portion of the vsftpd to activate and deactivate block on the file, hangs when client request a file from the server. This happens when seccomp_sandbox is enabled in the configuration.
vsftpd version is 3.0.3

Similar issue has been addressed on 3.0.2 and fixed on other distribution.
