libbpf: Fix for the potential undefined behavior due to shifting
When compiling libbpf with sanitation, ubsan will report the following:
```
left shift of 1 by 31 places cannot be represented in type 'int'
```
This may lead to undefined behavior according to the compiler implementation,
let's fix it by casting to unsigned counterpart before shifting.
