add Linux compat arg wrapper for ftruncate64(), and change linux compat

truncate64() wrapper to translate args structure
NetBSD truncate() and ftrucate() have hidden 'pad' argument, so we have
to do the argument translation

Problem found and patch supplied in PR kern/22360 by Ales Krenek

This is the last of syscalls with hidden 'pad' arg we didn't have
wrapper for; all the others (lseek, mmap, pwrite, pread) already had
wrapper before.
