parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes

commit e5f3e299a2b1e9c3ece24a38adfc089aef307e8a upstream.

Those return codes are only defined for the parisc architecture and
are leftovers from when we wanted to be HP-UX compatible.

They are not returned by any Linux kernel syscall but do trigger
problems with the glibc strerrorname_np() and strerror() functions as
reported in glibc issue #31080.

There is no need to keep them, so simply remove them.
