conf/bitbake.conf: allow cache reuse between bitbake, bitbake-layers and hob
BB_ENV_EXTRAWHITE is set by the bitbake wrapper script but not by bitbake-layers, and thus it was affecting the data hash and thus invalidating the cache. Any variables passed through from the environment by being added to this variable should themselves influence the hash already if they are not already excluded from, the data hash, so BB_ENV_EXTRAWHITE can be excluded. Similarly, DISABLE_SANITY_CHECKS is set by the hob script in order to have sanity checks run later, but not set by the bitbake wrapper script. It doesn't actually affect the build itself and so its value can also be excluded from the data hash. These changes prevent unnecessary reparsing between executions of bitbake, bitbake-layers, and the initial pseudo build within the hob script. Fixes [YOCTO #2680].
