MT#17215 Skip LVM workaround if FAI's setup-storage >=5.0 is present

The "--yes" workaround for LVM2 is needed for LVM versions
newer than >=2.02.106 to avoid a hanging prompt during
partition setup. Starting with FAI 5.0 the workaround
for this is included in FAI's setup-storage and therefore
we don't need our workaround any longer, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=750212

So ensure that fai-setup-storage is new enough, and only
if not then check the lvm2 package version and apply the
workaround as needed.

Fixes:

| Executing: lvcreate --yes --yes -n swap -L 1002.755859375 vg0
| (STDERR) Option -y/--yes may not be repeated.
