sim: Fix up the selectFunc syscall to work with g++ 10.2.
This is no longer willing to implicitly cast between the locally defined
Linux::fd_set type and the system fd_set type. That's pretty reasonable
since those types are really independent of one another, and we
shouldn't be using them interchangeably in the first place. That's a
pre-existing condition though, and I just want to get the existing code
to compile for now.
