[OE-core] [PATCH 1/2] package_manager.py: leave the __db.00* files in place

[Laurentiu Palcu]

Do not delete the __db.00* files in the PackageManager class. Leave this
operation up to the client classes. One side effect of this deletion was
the following message appearing in the output of the next rpm command
executed:

rpmdb: BDB1540 configured environment flags incompatible with existing
environment

We might also gain some time here by not deleting/creating those files
very often.
