[PATCH:libX11] Reject negative string counts in copy_string_list

[Alan Coopersmith]

Silences parfait warning of a potential memory leak:
   Memory leak of pointer 'dst' allocated with malloc(length)
        at line 160 of FSWrap.c in function 'copy_string_list'.
          'dst' allocated at line 145 with malloc(length).
          dst leaks when count <= 0 at line 154.
