Set `DEFCUDAVERSION` and `DEFSTDPARCOMPUTECAP` correctly in localrc for NVHPC

[damianam]

Without these changes those variables are not defined correctly. Example of the resulting difference:

-set DEFCUDAVERSION=12.3;
-set DEFSTDPARCOMPUTECAP=;
+set DEFCUDAVERSION=12;
+set DEFSTDPARCOMPUTECAP=80;
