selftests/bpf: Support struct/union presets in veristat
Extend commit e3c9abd0d14b ("selftests/bpf: Implement setting global
variables in veristat") to support applying presets to members of
the global structs or unions in veristat.
For example:
```
./veristat set_global_vars.bpf.o -G "union1.struct3.var_u8_h = 0xBB"
```
