Change log level

This log usually occurs if the dependent static library did not
exist on the system before, then an app and the library were
installed on an install session. If the library does not exist
and is not installed at same time, the installation will have
INSTALL_FAILED_MISSING_SHARED_LIBRARY error. So it is
unneccessary to log with wtf, use warning instead.
