[nvptx] Restore default to sm_30 

With commit 07667c911b ("[nvptx] Build libraries with misa=sm_30") the
intention was that the sm_xx for all libraries was switched back to sm_30
using MULTILIB_EXTRA_OPTS, without changing the default sm_35.

Testing on an sm_30 board revealed that still some libs were build with sm_35,
so fix this by switching back to default sm_30.

Tested on nvptx.
