lcfile: skip over any null entries in args list
Previous code seemed to assume that printf("%s", NULL) would result in a 0-length string, not "(null)" or similar, but since there's no point looking for files in "(null)/filepath...", instead we just skip over NULL entries in search paths when generating file names. In the *DirName() functions, this effectively just moves the "bail on NULL in arg[i]" check up from the later code that assigned it to targetdir and then bailed if that was NULL. Not sure how there ever could be a NULL in arg[i], given the current implementation of XlcParsePath, but it's easy enough to check once and reject up front instead of on every reference.
