[OE-core] [PATCH 0/2] wic: partition alignment and sizing fixes

[Maciej Borzecki]

A couple of fixes that were need for properly booting wic generated
images on beaglebone black. The firs one fixes an apparent problem
with the size of the first partition being changed unexpectedly. For
images with MBR, such as ones used for booting BBB, this resulted in
the first (boot) partition having an odd number of sectors. In such
case the board will not boot, so the default Yocto generated image
does not work.

The second patch fixes minor issue with realigning partitions.
Apparently, when realigning, the alignment would be added even if the
partition is already aligned. This will definitely waste some space,
having a larger impact on smaller images.
