Don't pass loginmsg by address now that it's an sshbuf*

In 120a1ec74, loginmsg was changed from the legacy Buffer type
to struct sshbuf*, but it missed changing calls to
sys_auth_allowed_user and sys_auth_record_login which passed
loginmsg by address. Now that it's a pointer, just pass it directly.

This only affects AIX, unless there are out of tree users.

Remove UNICOS support.

The code required to support it is quite invasive to the mainline
code that is synced with upstream and is an ongoing maintenance burden.
Both the hardware and software are literal museum pieces these days and
we could not find anyone still running OpenSSH on one.

OSX provides a getlastlogxbyname function that automates the reading of
a lastlog file. Also, the pututxline function will update lastlog so
there is no need for loginrec.c to do it explicitly. Collapse some
overly verbose code while I'm in there.
