scripts: clvmd: replace awk functionality with LVM's selection

No need to use awk now to get appropriate VGs/LVs, use LVM's
own --select - it's quicker, it removes a need for external
dependency on awk and it's also more readable.

WHATS_NEW

@@ -1,5 +1,6 @@
 Version 2.02.115 -
 =====================================
+  Use LVM's own selection instead of awk expressions in clvmd startup scripts.
   Do not filter out snapshot origin LVs as unusable devices for an LVM stack.
   Fix incorrect rimage names when converting from mirror to raid1 LV (2.02.112).
   Avoid excessive re-reading of metadata and related error messages in pvremove.
