selftest/reproducible: Allow packages exclusion via config

OEQA_REPRODUCIBLE_EXCLUDED_PACKAGES can be used to prevent known
not-reproducible packages to make the reproducible test fail.

For example, in local.conf:
  OEQA_REPRODUCIBLE_EXCLUDED_PACKAGES = "example-not-reproducible"

To quote the original exclusion commit (4864764667097b32a3ee1935e2c52df732d55632)
> selftest/reproducible: add an exclusion list for items that are not yet reproducible
> [...]
> Non-reproducible excluded packages are not given to diffoscope and do not cause a
> failure, but still saved side-by-side with non-reproducible failing ones to make
> investigation easier.

NB: Patch was written by Richard with small fixes and a commit message
from Yoann.
