do attempt to shade dependencies.

Was introduced in
49dc7bc
but this is a waste of space.

as the shade runs after the hpi package all that happens is that the
classess get copied into the root of the HPI.
classes are never loaded from here and there is a copy in
WEB-INF\lib\gcp-client-xxx.jar that is used, and this has been working
for a while.

whilst there may also be a gcp-client in other places that this plugin
has dependencies to I saw no gcp-client in google-oath-credentials
wheich would be the only logical place.  Additionally if it where not
broken before this fix it would remain not broken after this fix.
