syscall: don't fail if __NR_signalfd is not defined

3341e204dc syscall: don't fail if __NR_signalfd is not defined 
lxc fails to build if __NR_signalfd is not defined since version 4.0.0
and
bed09c9cc0

However, some architectures don't define __NR_signalfd but only
__NR_signalfd4. This is the case for example for nios2 or csky:
f9ac84f92f/sysdeps/unix/sysv/linux/nios2/arch-syscall.h
f9ac84f92f/sysdeps/unix/sysv/linux/csky/arch-syscall.h

seccomp: remove seccomp fd from event loop after task exited 
Linux v5.8 will land my patch where seccomp notifies when a filter goes unused,
i.e. when the last task using a given seccomp filter has exited. This wasn't
possible before and so we accumulated file descriptors in the container's event
loop whenever we attached to the container.
I'm not sure whether the task exiting before we could handle its syscall should
cause us to report and error or not. For now, let's simply close the event loop
and not report an error.

The rule added in 863845075d did not cover all
necessary mount calls for /proc/sys/kernel/random/boot_id
(in src/lxc/conf.c: lxc_setup_boot_id) - the ro remount is missing.
