Bug 1179885 - Update rust mp4parser gtest. r=k17e Switch to stdio for reading the file snippet. I can't figure out how to cleanly read a minimum subset into a vector with ifstream. Previously we were asking it to read zero bytes, so the argument validation in read_box_from_buffer() was rejecting the data without trying to parse it. With this and the v0.0.9 changes to catch eof, we can remove the expected fail on the street.mp4 test.
