pkg/sysinfo.New(), daemon.RawSysInfo(): remove "quiet" argument
The "quiet" argument was only used in a single place (at daemon startup), and
every other use had to pass "false" to prevent this function from logging
warnings.

Now that SysInfo contains the warnings that occurred when collecting the
system information, we can make leave it up to the caller to use those
warnings (and log them if wanted).
