Use crypto::InitNSSSafely to initialize NSS for remoting.
Use crypto::InitNSSSafely to initialize NSS for remoting.

It was doing it manually and missed DisableNSSForkCheck. This was working
because ppapi_plugin_main.cc contains a redundant call. This instance and
ppapi_plugin_main.cc's instance will be removed at different times (when
we can remove the internal remoting plugin and when we can assume the
chimera, respectively), so decouple the two to help set up the dominoes
for the future removal.
