ipatests: increase sosreport verbosity

With the new version sos-4.2-1, sos report -v prints the
debug messages into sos.log only. In order to see the debug
messages in the console, -vv is needed.
For more info refer to sos report commit
1d0729a9dc

Since the test is looking for messages in stdout, use -vv to
make sure the expected messages are printed in the console.
