tests: handle debug.log from clvmd

Browse Source 
When clvmd starts, it starts it's own command logging into debug.log.
This is interferring with our other command debug.log.
As as sideeffect we may experience log from command,
followed but lots of zeros and continued with clvmd log.

Fix it by renaming debug.log and now we could also print this trace
to get full list of clvmd activity nicely.

Also improve some post-mortem prints from udevadm and dmsetup to
make the output more usable.
