[OE-core] [PATCH] context: allow test execution with buildhistory unless version-going-backwards is present

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Users constantly running oe-selftest find annoying to disable buildhistory before running
'oe-selftest' then enabling after it. To lessen the buildhistory restriction, allow buildhistory
unless 'version-going-backwards' is present on ERROR_QA bitbake variable.

[YOCTO #11580]
