util/amdfwtool: Allow 0-length blobs
A side effect of the change 8e0dca05
"util/amdfwtool: Add generic image copy function"
was to treat a read operation of zero bytes as a failure. Some
implementations exist that use zero length files as a means of
removing functionality. This causes amdfwtool to exit with an
error.
Put the zero length capability back in, and generate the requested
table entry with a length field of 0x0.
TEST=Boot google/grunt, inspect PSP directory table
BUG=b:128507639
