unix: augment support for zos/s390x

This augments sys/unix support for zos/s390x by
adding a small number of syscalls:
Errno2
Err2ad
W_Getmntent_A (pure ascii version of W_Getmntent)
Select

It also makes Mount and Unmount more Linux-like.
A few necessary constants and types are added,
and some tests.

These changes do not affect other platforms in any way.

Fixes golang/go#45838
