[OE-core] [PATCH 3/4] buildhistory-extra.bbclass: simplify usage

[Patrick Ohly]

From: Ismo Puustinen <ismo.puustinen at intel.com>

Instead of expecting the user to put InHERIT += "buildhistory
buildhistory-extra" into the local.conf, now only listing
buildhistory-extra is needed because the base class will always
be inherited.

[Change from Ismo, commit message from Patrick]
