Add pread and pwrite 32bit syscall wrappers for parisc

Add pread and pwrite 32bit syscall wrappers for parisc

On the hppa arch (32bit userspace and 32 or 64bit kernel), the fstype
program fails to detect the filesystem.  The reason for this failure
is, that fstype calls the pread() syscall, which has on some
architectures with 32bit userspace a different calling syntax.  I
noticed this bug on hppa, but I assume s390 (32bit) and others might
run into similiar issues.
