core: set NoNewPrivileges for seccomp if we don't have CAP_SYS_ADMIN
The manpage of seccomp specify that using seccomp with SECCOMP_SET_MODE_FILTER will return EACCES if the caller do not have CAP_SYS_ADMIN set, or if the no_new_privileges bit is not set. Hence, without NoNewPrivilege set, it is impossible to use a SystemCall* directive with a User directive set in system mode. Now, NoNewPrivileges is set if we are in user mode, or if we are in system mode and we don't have CAP_SYS_ADMIN, and SystemCall* directives are used.
