test/py: android: Point fdt command to aligned addresses

Newer versions of libfdt strictly check whether the FDT blob
passed to them is at 8-byte aligned offset, if it is not, then
the library fails checks with -FDT_ERR_ALIGNMENT . Currently,
'abootimg get dtb --index=1 addr size' may return non 8-byte
aligned FDT address which points directly into the abootimg.
Copy the result into temporary location before validation to
avoid FDT alignment check failure.
