[parisc] open(2) compat bug

In commit 9d73fc2d ("open*(2) compat fixes (s390, arm64)") I said:
>
> 	The usual rules for open()/openat()/open_by_handle_at() are

Three exceptions, actually - parisc open() is another case like that.
Native 32bit won't force O_LARGEFILE, the same binary on parisc64 will.
