[OE-core] [PATCH 1/2] package.bbclass: fire an event with package info

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

On emit_pkgdata, the code writes a file with all the
package details like PN, PV, PR, LICENSE, etc...

In order to record package information on a remote client,
we also build out a custom event with this information
and fire it.

This will not have any performance impact, and allow
us to retrieve data about built packages from a
remote build server.
