WMaker: fix dangerous code in file scanning for wAdvancedInputDialog (Coverity #50172)

Browse Source 
As pointer by Coverity, the function wstrappend may move the string in
memory (because that's what realloc does if it can't expand the allocated
buffer in-place), so it is important to use the returned address and not
assume the old pointer is still valid.
