Bug#986129: unblock: sendmail/8.15.2-22

[Andreas Beckmann <anbe@debian.org>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Please unblock package sendmail

sendmail does not cleanly restart after upgrading from buster because
the binaries were moved from /usr/lib/sm.bin to /usr/libexec/sendmail.
So let's stop sendmail in preinst if upgrading from a version with the
old layout. (To minimize downtime sendmail is usually not stopped before
the new version gets unpacked, but only restarted in postinst.)

unblock sendmail/8.15.2-22
