Subject: [PATCH] test: add large tests skip option

The lvm2 test suite aims at small test resource footprints
(few PVs, small PV sizes) to run on tmpfs backed loop device.

OTOH, lvconvert-reshape-raid.sh aims to test the maxima of
supported total stripes of 64.  This patch adds a prerequisite
conditional to skip tests using more than 14 stripes.

It requires the target version 1.13.1 to avoid deadlocks.
