Move BND configuration to pom.xml (#3065)

This removes the BND configuration in `log4j-1.2-api/bnd.bnd` and moves it to the POM file.

The resulting JPMS module has the same requirements as version `2.24.1`.

```
requires java.base
requires java.desktop
requires java.management transitive
requires java.xml transitive
requires javax.jms-api static
requires org.apache.logging.log4j transitive
requires org.apache.logging.log4j.core static
```
