Remove PackageHub Activating code for w3m_https

Pkg "w3m" is not in "Packagehub" now (at lease on sle12sp5, sle15sp2)
so delete the invoking of "setup_web_browser_env()" which activates
"Packagehub", "Packagehub" activation usually fails as it is not ready
at the early developing stage (see bug#1175578).
