swupd-image.bbclass: remove assumption about OS version numbering
It is not guaranteed that OS versions always increment in steps of 10 and that deltas are desired for "current version - 10, -20, etc.". For example, previous versions might be 10, 20, and the current one 21 because it is a minor update. In such a case no delta packs would be generated because OS versions 11 and 1 do not exist. Ostro OS outside of the CI derives the OS version from datetime, which leads to high version numbers like 33014500. Counting down from that in steps of ten in shell under pseudo was surprisingly slow and unusable, running for minutes without even getting close to completion when it does not hit existing version numbers. So now the simplified approach is to generate delta packs for exactly the last SWUPD_N_DELTAPACK older versions, regardless what their numbering is. If a more sophisticated approach is needed, it can still be added later on, for example as part of YOCTO #9321. Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>
