sdcard_image: align partitions with flash pages
* Align partitions for SD card performance/wear optimization. For more
details, please see:

# Modifications to align partitioning by Steve Sakoman
# based on work by Arnd Bergmann
# Align partitions for SD card performance/wear optimization
# FAT partition size is 131072 sectors (64MB) less:
# MBR - 1 sector
# padding to align to the page size of the underlying flash - 127 sectors
# so we start the first partition at sector 128 and make it 131072 - 128 = 130944 sectors
# second partition starts at 131072 and continues to fill the card
