users.7: Standard user account names

[temcbun_gmail.com]

Summary

This is a follow-up for the https://reviews.freebsd.org/D54114, where groups(7) is introduced.

Here the users(7) is ported from NetBSD with appropriate changes to user names and descriptions. In addition to that, the FILES section was added.

In the users(7) page I described all the standard base system users found in /usr/src/etc/master.passwd, except user 'uucp', which I honestly don't know the purpose of.

Obtained from: NetBSD

share/man/man7/users.7

74–81

This is the part that I added (NetBSD version doesn't have it). I believe this information may be useful for some users to understand what the toor account can be used for. Besides, here we warn about potential problems when altering the root shell.

211–217

This is true for NetBSD, but I'm not sure if that applies to FreeBSD as well.

Forgot to include users.7 in MAN variable in Makefile.

Reference users.7 in intro.7.

Can we have it in 15.1? I guess it would be reasonable, since we already have groups(7) there. They look better together.

I actually did not merge groups.7 into 15.1. This was my mistake. Let me see if I can address that.

@ziaee So, would it be possible? :)
