Bug#387699: exim4: Should create /var/run/exim4/ if it is missing

Why, if the packages using /var/run/<directory>/ are updated to create
these directories if they are missing after boot?  As far as I can
see, there are not very many such packages including directories in
/var/run/ as part of the package (crack and crack-md5 according to
apt-file), and probably a few more creating a directory in the
postinst.

Moving these directories to tmpfs will make it easier for LTSP and
other stateless workstation environment too.

I expect the new sysvinit package to be uploaded to unstable in about
a week.
