[OE-core] [PATCH 1/2] bitbake.conf: Move default hash policy initialization before conf file inclusion

[Jason Wessel]

It is desirable to be able to augment the default hash policy from
local.conf if adding new exported variables that do not impact the end
result of a build, and in order to do this the default initialization
must occur prior to the conf file inclusion.

This is an example of a change that should not impact the sstate sum
that an end user might change in the local.conf.

export CCACHE_DISABLE = "1"
BB_HASHBASE_WHITELIST += "CCACHE_DISABLE"

There are a myriad of reasons you might set this ranging from
debugging a ccache issue to the desire to never construct the ccache
at all, either way the end result of the binaries produced is always
the same.
