[LTP] [PATCH v5 2/3] Add LVM support scripts

[Martin Doucha <mdoucha@suse.cz>]

Add support scripts for LVM tests that can be used with external testing tools.
- generate_lvm_runfile.sh - Creates runtest/lvm.local with testcases for all
  locally supported FS types
- prepare_lvm.sh - Creates 2 LVM volume groups and mounts logical volumes
  for all locally supported FS types
- cleanup_lvm.sh - remove LVM volume groups created by prepare_lvm.sh and
  release the associated loop devices

Signed-off-by: Martin Doucha <mdoucha@suse.cz>

Changes since v1:
- rename generate_runfile.sh to generate_lvm_runfile.sh
- update above commit message

Changes since v2:
- fix filename in misc/lvm/Makefile

Changes since v3:
- LVM volume size increased to 1GB
- cleaned up some useless code in runfile template
- test cases with `growfiles -L ...` limited to 768MB of disk space

Changes since v4:
- rebase only
