Add sbin and /usr/local directories to _PATH_DEFPATH.

Set _PATH_DEFPATH to
/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin. This is the
path in the default class in the default /etc/login.conf,
excluding ~/bin which would not be expanded properly in a string
constant.

For normal logins, _PATH_DEFPATH is overridden by /etc/login.conf,
~/.login_conf or shell startup files. _PATH_DEFPATH is still used as a
default by execlp(), execvp(), posix_spawnp() and sh if PATH is not set, and
by cron. Especially the latter is a common trap (most recently in PR
204813).

Fix the email address formats in some posix_spawn(3) manpages.

It seems I made a small bug when writing some of the posix_spawn(3)
manpages. Remove the redundant "Ed Schouten", which broke the AUTHORS
section.
