[OE-core] [PATCH 1/9] classes/buildhistory: remove obsolete flat package history feature

[Paul Eggleton]

Remove the ability to set BUILDHISTORY_KEEP_VERSIONS = "1" to save the
package history as flat versioned files rather than relying on git to
keep previous versions of the package information. git has proven to
work quite well in this capacity.
