Add addDependencyBasedRequires configuration option

[EagleErwin]

If you specify rpm dependencies in your pom.xml like this...

<dependency>
    <groupId>my.group.id</groupId>
    <artifactId>artifact</artifactId>
    <version>1.1.0</version>
    <type>rpm</type>
</dependency>

... and set the addDependencyBasedRequires to true in the configuration of the rpm-maven-plugin, the changes in this PR will make sure that an RPM Requires is added for the specified version (or larger).

It is (in this example) equivalent to setting this in the configuration of the rpm-maven-plugin:

<requires>
    <require>my.group.id.artifact &gt; 1.1.0</require>
</requires>

This implementation requires the rpm executable to be present on the build environment for getting the required information from the dependencyArtifact file.
