fix: exclude maven metadata and jacoco from shaded JAR

Excluding maven metadata fixes the following warning from
`deployDistribution.sh`:
```
[WARNING] Artifact org.jlab.coat:coat-libs JAR (about to be
installed/deployed) contains Maven Plugin metadata for conflicting
coordinates: org.jacoco:jacoco-maven-plugin. Your JAR contains rogue
Maven Plugin metadata. Possible causes may be: shaded into this JAR some
Maven Plugin or some rogue resource.
```

Excluding `jacoco` since only used here for coverage testing
