Remove useless pstrdup() calls.

Browse Source 
The result of PLyUnicode_AsString is already palloc'd,
so pstrdup'ing it is just a waste of time and memory.
More importantly it might confuse people about whether
that's necessary.  Doesn't seem important enough to
back-patch, but we should fix it.  Spotted by Coverity.
