    seccomp: cap SECCOMP_RET_ERRNO data to MAX_ERRNO
    
    BugLink: http://bugs.launchpad.net/bugs/1496073
    
    The value resulting from the SECCOMP_RET_DATA mask could exceed MAX_ERRNO
    when setting errno during a SECCOMP_RET_ERRNO filter action.  This makes
    sure we have a reliable value being set, so that an invalid errno will not
    be ignored by userspace.
