[OE-core] [PATCH] base.bbclass: trim duplicated whitespaces from BUILDCFG_VARS

[liu.ming50 at gmail.com]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

To give a example:
Before the change, in our build console, TUNE_FEATURES looks like:
...
TUNE_FEATURES     = "arm armv7a vfp  neon        cortexa8"
...

After the change:
...
TUNE_FEATURES     = "arm armv7a vfp neon cortexa8"
...
