[PATCH v6 3/5] Add dependency of dracut lvmthinpool-monitor module

[Tao Liu]

The 80lvmthinpool-monitor module is needed for monitor and
autoextend the size of thin pool in 2nd kernel. The module was
integrated in dracut version 057.

If lvmthinpool-monitor module is not found, we will print a warning.
Because we don't want to block the kdump process when the thin pool
capacity is enough and no monitor-and-autoextend actually needed.
