[PATCH 5/5] poky.conf: whitelist shell variables which are volatile to build system

[Kevin Tian <kevin.tian@intel.com>]

Bitbake preserves a list of good shell variables which are required by some
shell based tasks. When scheduling a new shell task, bitbake always appends
all those shell variables which become a trouble for task checksum, because
most of those variables (GNOME_KEYRING_PID, XDG_SESSION_COOKIE, etc.) are
specific to the build system and desktop session.

Previously I came up an approach to explicitly seperate external shell variables
from the ones defined by bitbake, which however ends up to be complex.

So here I simply whitelist all preserved shell variables from current definition.
This should allow wider test on sstate when the better option is under discussion.
