Use statvfs64() for pathconf(_PC_NAME_MAX).
pathconf(_PC_NAME_MAX) was implemented on top of statfs(). The 32bit
version therefore fails EOVERFLOW if the filesystem blockcount is
sufficiently large.
Most pathconf() queries use statvfs64(), which avoids this issue. This
patch modifies pathconf(_PC_NAME_MAX) to do likewise.
