[prim_util_pkg] Fix DC warning in _clog2()

DC warns about assigning to an input port (`value`). Use an intermediate
variable instead.

```
Warning:  ../src/lowrisc_prim_util_0.1/rtl/prim_util_pkg.sv:30: Port value of type input is being assigned.  (VER-1005)
Warning:  ../src/lowrisc_prim_util_0.1/rtl/prim_util_pkg.sv:32: Port value of type input is being assigned.  (VER-1005)
```
