[PATCH v2] meta: Do not warn on usage of env vars exported to bb fetcher

["'Tobias Schaffner' via isar-users" <isar-users@googlegroups.com>]

Only a few of the variables allowed to be exported to the bitbake
fetcher, are ignored when warning about env exports in the
dpkg.bbclass.

Reference the list in bitbakes fetcher2 module instead of maintaining
a additional incomplete list.
