Refine boot process of build target and allow config of /boot fstype and mount-options

- Add env-vars BOOT_FSTYPE and BOOT_FSOPTIONS, supporting customizing the boot filesystem type and options
- FAT_CODEPAGE (if using BOOT_FSTYPE vfat, default) is hardcoded '437'

- Add 'lsof', allowing to check open listening ports (besides netstat)

- On Raspi: Use plymouth splash screen for all configurations, theme 'pix'

- Add systemd resize2fs_once.service to have it start very early
  to resize the rootfs partition for RW rootfs

- No kernel argument 'rootwait' for initramfs/grub root=file boot

loop_rootfs (initram):
- kill spawn-off pipe copy process (LOOP_ROOTFS_LOG_PIDS)
- Use BOOT_FSTYPE, BOOT_FSOPTIONS (incl mounting /boot)..
- Use dedicated fsck.BOOT_FSTYPE if possible (and quiet)
- Log fsck and mount attempts, failure and success
-

Stage2 01-sys-tweaks fixes:
- Only disable systemd-remount-fs for ROOTFS_RO
- Only generate /boot/loop_rootfs.id for ROOTFS_RO
- Kernel Modules: Add codepage 437 and 850, drm and vc4 (raspi only)
- Use TARGET_ARCH in all situations
- On RW rootfs, grub-install with ext2 module
