perf machine: Guard against NULL strlist in machines__findnew()
The static 'seen' strlist caches guestmount paths that have already
been reported as inaccessible, to avoid repeating the error message.
If strlist__new() fails (OOM), 'seen' stays NULL and the next call
dereferences it via strlist__has_entry() and strlist__add().
Guard both calls so that on allocation failure the error message is
still printed (just not deduplicated) instead of crashing.
Fixes: c80c3c269011 ("perf kvm: Limit repetitive guestmount message to once per directory")
