Trying to connect once without a polkit agent will generate an error on the
server side which seems too rough given it only serves the purpose of the client
(virsh in this case) to figure out that an agent is needed. Thankfully we can
just try running the agent. It does not break anything as we are running it
with `--fallback`, which makes sure it does not replace an existing agent in
case there is one already registered.
The second piece of code trying to start the polkit text agent is kept in order
to _really_ try out starting the agent (and error out when failing to do so)
just in case the agent was not available the first time it was ran. Even though
it should not happen it avoids a very rare race condition and really does not
add much complexity.

Recently, FreeBSD has got sched_get/setaffinity(3) implementations and
the sched.h header as well [1]. To make these routines visible,
users have to define _WITH_CPU_SET_T.
This breaks current detection. Specifically, meson sees the
sched_getaffinity() symbol and defines WITH_SCHED_GETAFFINITY. This
define unlocks Linux implementation of virProcessSetAffinity() and other
functions, which fails to build on FreeBSD because cpu_set_t is not
visible as _WITH_CPU_SET_T is not defined.
For now, change detection to the following:
- Instead of checking sched_getaffinity(), check if 'cpu_set_t' is
available through sched.h
- Explicitly check the sched.h header instead of assuming its presence
if WITH_SCHED_SETSCHEDULER is defined
