flash: Move image manager tmpfile config

1e4452449 added a systemd tmpfile config file for the software image
upload path but the config file was added to the systemd recipe.
tmpfile config files should be added to the recipes/config files that
use them.  For example on an RPM based distro:

$ rpm -qf /usr/lib/tmpfiles.d/samba.conf
samba-common-4.7.7-0.fc27.noarch

Tested: Validated software.conf present in Witherspoon rootfs
