[OE-core] [PATCH] scripts/oe-buildenv-internal: Fix regression in BB_ENV_EXTRAWHITE setting

[Otavio Salvador]

The commit OE-Core:ada4639 (oe-buildenv-internal: simplify derivation
of BB_ENV_EXTRAWHITE) changed the format of BB_ENV_EXTRAWHITE
variable to:

,----
| BB_ENV_EXTRAWHITE='ALL_PROXY
| BB_NO_NETWORK
| BB_NUMBER_THREADS
| ...
| '
`----

Instead of:

,----
| BB_ENV_EXTRAWHITE='ALL_PROXY BB_NO_NETWORK BB_NUMBER_THREADS...'
`----

The old format allow for external script parsing easier and there is
no need to change the format as it has no benefit from usage
perspective.
