cgpt_wrapper: Only write rw_gpt back if changed

We always wrote back the rw_gpt file to NOR flash. This operation is too
slow. This CL compares if the original file has been changed by cgpt.bin
before writing the file back to NOR.

BUG=None
BRANCH=None
TEST=/usr/bin/cgpt show /dev/mtd0 now does not write back to NOR
