mail(1): use "sendmail" as argv[0] for sendmail

[Lauri Tirkkonen]

For some reason mail(1) is using "send-mail" as argv[0] for sendmail.
/etc/mailer.conf and smtpctl handle this identically to "sendmail", so
it seems a bit redundant. This diff makes mail(1) use "sendmail" as
argv[0], possibly allowing that duplication to be removed later from
mailer.conf and smtpctl.

Noticed while porting mail(1) to Unleashed (where we also have
mailwrapper, but no default configuration for "send-mail").
