Improve yang-maven-plugin error reporting for errors in dependencies

Improve yang-maven-plugin error reporting for errors in dependencies

Instead of e.g. this: [ERROR] yang-to-sources: Unable to parse yang
files from
/home/vorburger/dev/ODL/git/netvirt/vpnservice/aclservice/impl/src/main/yang
java.util.zip.ZipException: invalid LOC header (bad signature) at
java.util.zip.ZipFile.read(Native Method)

it will now report the much more useful variation like this:
java.io.IOException: Exception when reading from:
/home/vorburger/.m2/repository/org/opendaylight/netvirt/neutronvpn-api/0.3.0-SNAPSHOT/neutronvpn-api-0.3.0-SNAPSHOT.jar::META-INF/yang/neutronvpn.yang
	at (...)
Caused by: java.util.zip.ZipException: invalid LOC header (bad
signature)

similar to earlier https://git.opendaylight.org/gerrit/#/c/42193/
