Reproducibility: crash if <mapname>.lin file missing.

problem: vfsLoadFullPathFile returns -1 if the file is missing, apparently it
used to return 0 (which could be confused with an empty file), this caller code
was not updated to check for -1.
fix: change the == 0 on radiant/points.cpp line 155 to <= 0

P.S. I found more occurences of this mistake elsewhere in radiant:
plugins/eclassfgd/plugin.cpp line 645 (identical bug - crash if file missing)
radiant/eclass_def.cpp line 283 (identical bug - crash if file missing)
radiant/texwindow.cpp line 1251 (this might crash if the shader file is 0 bytes)
