build and packaging for Raspbian. Added raspbian_package
target to makefile.

Removed the SysVInit init and system service files from the scripts
subdirectory and added them to the packaging templates. Debian
(and therefore also Ubuntu packaging) expect the init and service
files in the packaging subdirectory from there debuild will pick
them up automatically. Also adjusted the rules files in debian_template
and ubuntu_template to remove the explicit copy of the init file.

Added yocto_template to hold the init/service files for Yocto Project
builds.

Now all SysVInit init scripts and systemd service files are maintained
with their respective OS template which makes things more transparent
and compliant with the respective OS packaging rules.

1. Minor typo fixes in Makefile
2. rvi.postrm should not remove /etc/rvi
3. systemd rvi.service
   a) incorrect path for HOME
   b) when starting daemon from shell script RemainAfterExit=yes
      needs to be added to prevent systemd from calling ExecStop
      right after ExecStart.

For some reason the tab in Makefile got replaced with spaces.
Converted them back so that make does not complain about
incorrect indentation.

the target sysroot can be stripped off the installation path.
