vmcore: reorganize configuration

vmcore is an ABRT addon (resp. plugin) so its configuration file should be
placed in plugin configuration directory.

All addons configuration files have name consisting from addon's name
and '.conf' suffix

Manual page for an addon configuration file should have prefix 'abrt-'
in order to avoid users confusion.
