wmaker: do not duplicate a string that does not need to be (Coverity #72814)

Browse Source 
As coverity pointed, the duplicated string was never freed. Considering
what is done with it, is not necessary to allocate a duplicate for it, it
is a waste of time and participates in memory fragmentation.
