[LTP] [PATCH 1/1] prepare_lvm.sh: Use $TMPDIR instead of custom $LVM_DIR

[Petr Vorel]

Allow users to reuse TMPDIR environment variable instead of forcing them
to export LVM_DIR, which would behave the same as TMPDIR.

LVM_DIR is undocumented users expect TMPDIR.

Fixes: 0838220f25 ("prepare_lvm.sh: Allow to define tmp directory")

Hi,

it was me who introduced LVM_DIR, but thinking about it twice it was not
a good idea.

Kind regards,
Petr
