[OE-core] [PATCH 2/4] package_deb: check CONFFILES exist before adding them to metadata

[Ross Burton]

dpkg-deb verifies that conffiles exist, so verify that the specified files
actually exist before writing them to conffiles.

This mirrors the behaviour of FILES and package_rpm's CONFFILES handling.
