kernel: defconfig updates
enable some kernel features: EXT4_FS, FANOTIFY: alignment on agl-spec section 7.4.1., POSIX_MQUEUE: standard efficient Posix ipc mechanism, TUN: useful for a VPN link establishment on V2I use-case, when distro is built with debug-tweaks: LOOP: for LTP testcase better coverage, Signed-off-by: Yannick Gicquel <yannick.gicquel@iot.bzh>
