shr-image: remove /boot from jffs2/ubi/ubifs images only on om-gta01
shr-image: remove /boot from jffs2/ubi/ubifs images only on om-gta01

* om-gta02 has usually enough space on NAND
* qi-bootmenu can use those kernels and supports only om-gta02 now
* also make sure -boot is empty before moving /boot there
* move /boot back even when last command mkfs.ubifs/ubinize/mkfs.jffs2 fails (no && here)
