ximcp: Prevent memory leak & double free if multiple %L in string

In the highly unlikely event that TransFileName was passed a path
containing multiple %L entries, for each entry it would call
_XlcFileName, leaking the previous results, and then for each entry it
would copy from that pointer and free it, resulting in invalid pointers
& possible double frees for each use after the first one freed it.
