[PATCH 1/2] spec, Makefile: add /etc/nvme files to package files

[sagi@grimberg.me (Sagi Grimberg)]

This way it can automatically be removed upon uninstallation
and we don't need %preun target. Also, this will also allow
to get these files on manual installation from sources.

Also, don't settle on the "file exists" check, use the '-s'
to check that it is not empty as well.

Lastly, in order to have hostnqn and hostid updated upon pkg
install, we have install-spec target that would omit hostnqn and
hostid files, and let the rpm %post do it (otherwise we
use the normal install target).
