NaCl: Stop building ppapi_proxy (libppruntime) as a user library
NaCl: Stop building ppapi_proxy (libppruntime) as a user library

We no longer need to need to build ppapi_proxy in nacl_env now that
I've removed the irt=0 build option from the NaCl side, and now that
I've fixed a test that was accidentally bypassing the IRT.

This change should make the NaCl build faster since it will compile
ppapi_proxy once rather than twice.  It should also stop us bypassing
the IRT accidentally.
