machined needs access to the host mount namespace to propagate bind
mounts created with the "machinectl bind" command. However, the
"ProtectKernelLogs" directive relies on mount namespaces to make the
kernel ring buffer inaccessible. This commit removes the
"ProtectKernelLogs=yes" directive from machined service file introduced
in 6168ae5.
Closes #14559.
