ar71xx: seama: fix making factory images

Browse source 
rootfs part needs to be aligned to erase block size which is passed as
the 6th argument to Image/Build/Seama  and is now 65536 since commit
commit 5119ee9 "ar71xx: fix bogus hardcoded kernel image size for Seama
images (fixes #20585)", but $(($(6) - 64)) still assumes that the
argument is a limit on kernel partition size, i.e. 1310720, so the
generated factory image is wrong in that the kernel will fail to find
the rootfs (FlySpray link at [1])

This patch will workaround it with the following steps

1. Calculate the required space for seama header and META data in step 5
2. Pre-padding 64 bytes to lzma-compressed loader
3. Generate correctly padded image-$(2).tmp
4. Strip out the padding
5. Seal it with seama utility

While at it convert seama to new build method

[1] FS#35 - mynet-n750 factory images don't find root partition,
