test: add large tests skip option

Browse Source 
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.
