lzma: Port size-checking ulzman() version to coreboot

Hardware / Coreboot - Julius Werner [chromium.org] - 12 February 2016 15:00 UTC

We've had a second version of ulzma() that would check the input and output buffer sizes in libpayload for a while now. Since it's generally never a bad idea to double-check for overruns, let's port it to coreboot and use it where applicable. (This requires a small fix in the four byte at a time read optimization we only have in coreboot, since it made the stream counter hit the end a little earlier than the algorithm liked and could trigger an assertion.)

BRANCH=None BUG=None TEST=Booted Oak, Jerry and Falco.
