16 Dec 21 Linux vgs port for HPUX (updated to work with vg version 2.2)

A while back, I came across a port of the very nice linux vgs command for HP-UX. A h/t to Juan Manuel Rey (juanmanuel.reyportal@gmail.com) for that original version.

But, upon using it recently, I noted it was not working now that we have some volume groups with vg version 2.2. Here is a modified version of the script that works for version 2.2 volume groups!

#!/sbin/sh
#
# vgs.sh - script to emulate the Linux LVM command vgs in HP-UX 11iv3
