build_artifact: Be more specific when searching for full payloads

A recent CL (CL:1427346) broke the CQ because the devservers weren't
able to identify the actually payload from three file examples:

chromeos_R74-11727.0.0-rc1_bob_full_dev.bin
chromeos_R74-11727.0.0-rc1_bob_full_dev.bin.json
chromeos_R74-11727.0.0-rc1_bob_full_dev.bin.log

which are the files we need in future for applying payloads.

This CL, fixes the build_artifacts to be more specific by only searching
for files with regular expression *_full_*bin instead. That way it will
ignore the .json and .log files.
