Subject: [PATCH] Replace the pkgrel variable with the release number of the
 build system

The PKGBUILD file must contain one of the following placeholders:
pkgrel=@RELEASE@
pkgrel=@RELEASE1@
pkgrel=@RELEASE2@

Assuming the $RELEASE variable supplied by the build system contains the value "123.456"
(default <CI_CNT>.<B_CNT>), the corresponding placeholder is replaced as follows:
pkgrel=123.456
pkgrel=123
pkgrel=456

@RELEASE1@ and @RELEASE2@ have been implemented in case someone wants
to use a stricter variant with only one number.
Then you have the choice between <CI_CNT> or <B_CNT>

For the use of obs-service-set_version an adjustment is necessary there.
I will link the corresponding pull-request here later.
