Fix bug #8114: LyX does not retrieve negative bbox parameters

LyX fails to read the bounding box from an EPS file if it has
negative values. Adjusting the regex will overcome this problem.
Negative values do not pose big problems later on, but the GUI
doesn't handle it correctly yet (see bug #5718).
