[LTP] [PATCH v2 1/1] prepare_lvm.sh: Allow to define tmp directory

[Petr Vorel]

Many distros don't have enough /tmp size for LVM tests, thus
allow to set $LVM_DIR to use different temporary directory.

Most of the space take backing files ($LVM_IMGDIR), but for consistency
changed both directories. $LVM_TMPDIR requires to update
generate_lvm_runfile.sh.
