I think you can use ardour.  Create a new project at 48000 and import 
your 44100 wav file.  Ardour does very good sample rate conversion.  
Upon import you'll have an ardour project at 48000.  Drag and drop 
the imported waveform onto a channel in the editor window, then 
select that track and export the selection as a wav file.  That 
should do it.  Find out more on ardour-users.  Cheers....
