pom: Add compatibility for JDK14

[TrackerSB]

In JDK14 the automatic module name resolution seems not to be sufficient. Specifying the automatic module name explicitly fixes the problem.

[V-F]

Could you please as part of this fix also move the java.nio.file.spi.FileSystemProvider from the sshd-core module to the sshd-common module where the implementation of this provider is located, since in the modular application the following exception will be thrown:

Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for C:\Users\V-F\.m2\repository\org\apache\sshd\sshd-core\2.4.0\sshd-core-2.4.0.jar
Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class org.apache.sshd.common.file.root.RootedFileSystemProvider not in module
