[OE-core] [PATCH 1/2 v2] qemurunner: Added host dumps when there are errors

From: Mariano Lopez <mariano.lopez at linux.intel.com>
This adds an instance of HostDumper to qemurunner,
with this instance now is possible to get dumps
from the host when there is an error.
This adds dump points in the next cases:
- runqemu exits before seeing qemu pid
- Fail to get qemu process arguments
- Not reach login banner before timeout
- qemu pid never appears
This also modifies the constructors of BaseDumper,
HostDumper and TargetDumper, they don't require
the datastore anymore, but the feature to replace
datastore variables has been lost (never used)
