Wrong prototype for listcreate()

[Jeroen Demeyer <jdemeyer@cage.ugent.be>]

Hello,

I know listcreate() is redundant, obsolete and shouldn't be used, but at 
least the prototype should be correct: it still says D0,L, but the 
argument was dropped from the libPARI function listcreate().

Cheers,
Jeroen.
