dmeventd: resolve compilation of vdo status parsing

A bit of chicken & egg problem - dmeventd needs to use old libdm library.
VDO is only part of new device_mapper internal library.

So include directly source file for parsing status - this fixes usability
problem of VDO plugin introduced with previous Makefile reshaping
patchset.

NOTE: source file needs to be keep then compilable in both environments.

Also add missing copyright header.
