strip quotes from LV names

On openSUSE 12.2 with LVM version lvm2-2.02.84-26.12.1 output of lvscan
contains quoted device names, like:

bor@opensuse:~> sudo /sbin/lvscan
  ACTIVE            '/dev/system/swap' [1,00 GiB] inherit
  ACTIVE            '/dev/system/root' [70,00 GiB] inherit
  ACTIVE            '/dev/system/home' [120,00 GiB] inherit
  ACTIVE            '/dev/system/datastore' [70,00 GiB] inherit

Current BIS code appends final quote to name.

Use lvs instead to get all information at once. Example of lvs output
for the same volumes:

bor@opensuse:~> sudo /sbin/lvs --nameprefixes --noheadings --options lv_name,vg_name,lv_size,lv_attr --units s
  LVM2_LV_NAME='datastore' LVM2_VG_NAME='system' LVM2_LV_SIZE='146800640S' LVM2_LV_ATTR='-wi-ao'
  LVM2_LV_NAME='home' LVM2_VG_NAME='system' LVM2_LV_SIZE='251658240S' LVM2_LV_ATTR='-wi-ao'
  LVM2_LV_NAME='root' LVM2_VG_NAME='system' LVM2_LV_SIZE='146800640S' LVM2_LV_ATTR='-wi-ao'
  LVM2_LV_NAME='swap' LVM2_VG_NAME='system' LVM2_LV_SIZE='2097152S' LVM2_LV_ATTR='-wi-ao'

Merge branch 'fu/lvm-quote'
collect /dev/disk/by-id as well

/dev/disk/by-id is often used in bootloader configuration
files, but cirrently it is hard to find out which /dev/sdXXX
they are. So collect /dev/disk/by-id as well.
