fix(lvm): clean up whitespace in messages

The lvm module has been printing messages with whitespace damage:

  Scanning devices sda sdb  for LVM logical volumes vg/root
  vg/swap

Remove the trailing space after the final device name, and remove the
newlines between LV names.  The message above becomes:

  Scanning devices sda sdb for LVM logical volumes vg/root vg/swap

(The same change is made to the VG activation message.)
