halimg: Add hal-rpmdb-checker.service to check rpm version compatibility

For removing the h/w dependency from Tizen core image, decide to create
Tizen core image (core.img) and hal.img separately. It means that each
image is able to be built on different build time. So that in order to
guarnatee the compatibility between images, must need to check
the version compatiblity of rpm packages of hal backend packages in hal.img.

hal-rpmdb-checker.service will check the  the version compatiblity
between core.img and hal.img on booting time.

If there are no problem between images, hal-rpmdb-checker script
will create /opt/etc/hal/.hal-img-version.ini with hal.img build
information. Also, after writing the core.img, hal-rpmdb-checker
script will create /opt/etc/hal/.first-booting file to distinguish
whether booting is first or not.

Exmaple of /opt/etc/hal/.hal-img-version.ini
$cat /opt/etc/hal/.hal-img-version.ini
tizen-6.5-unified-gbm_20210525.030006;
