[BugFix] pathfuncs.c path_append_ex basepath_max might cause buffer ovfl

strlcpy returns the length of the string that would have been copied
had there been sufficient space basepath_max might still be
larger than buf_size yet smaller than len
which would result in a null terminator being written past buf[buf_size-1]
