[API CHANGE] call ftruncate instead of ftruncate_by_name

The actual point of this change is making osl_fileOpen faster by
avoiding constructing and storing an OString. But that requires changing
to using ftruncate on the filehandle, which is arguably more
correct anyway, using the filename to truncate in the presence
of unlink() is dubious
