Truncate vbmeta size to partition size

Currently, avb assumes all vbmeta* partitions to have size of 64K, which
is maximum size possible. This wastes some memory as avb need to
allocate sufficient memory to hold the entire partition data. Instead,
try to detect the partition size, and only allocate minimum memory
needed to hold the partition data.
