Remove scoverage dependency from POMs

[mpilquist]

The cats-core 0.4.1 POM has the following entries:

        <dependency>
            <groupId>org.scoverage</groupId>
            <artifactId>scalac-scoverage-runtime_2.11</artifactId>
            <version>1.1.0</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.scoverage</groupId>
            <artifactId>scalac-scoverage-plugin_2.11</artifactId>
            <version>1.1.0</version>
            <scope>provided</scope>
        </dependency>

These should be removed, via pomPostProcess perhaps.
