vmm: Improve "cloud-hypervisor --help" view format

Browse Source 
Rust documentation comments follows 80 char per line. But some of
these help options doesn't have space in between. Longlines of
text is starting from beginning of the next line instead of
proper format.

Before fix:

Options:
  --cpus            boot=<boot_vcpus>,max=<max_vcpus>,topology=<threads_per_core>:<cores_per_die>:<dies_per_package>:<packages>,kvm_hyperv=on|off,max_phys_bits=<maximum_number_of_physical_bits>,affinity=<list_of_vcpus_with_their_associated_cpuset>,features=<list_of_features_to_enable>

After fix:

Options:
  --cpus            boot=<boot_vcpus>, max=<max_vcpus>,
                    topology=<threads_per_core>:<cores_per_die>:<dies_per_package>:<packages>,
                    kvm_hyperv=on|off,
                    max_phys_bits=<maximum_number_of_physical_bits>,
                    affinity=<list_of_vcpus_with_their_associated_cpuset>,
                    features=<list_of_features_to_enable>
