[OE-core] [PATCH 1/1] toaster.bbclass: do not fail on non-existent files

[Paul Eggleton]

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

Toaster may look up inexistent file paths in the build history
for packages that have been referenced but not built.

This triggers a failure, and this patch recovers by deleting
the reference to the non-built packages.
