[OE-core] [PATCH 1/2] bitbake.conf: add STAMPS_DIR for constructing STAMP

[Robert Yang]

Add STAMPS_DIR for constructing STAMP, the defination of STAMP is:

STAMP = "${TMPDIR}/stamps/${MULTIMACH_TARGET_SYS}/${PN}/${EXTENDPE}${PV}-${PR}"

We can only change the TMPDIR if we want to change the STAMP's location,
but the bb_cache.dat would be regenerated if TMPDIR changes, so add
STAMPS_DIR for constructing it, and add it to the BB_ENV_EXTRAWHITE,
this is very usefull for the "bitbake -S", since then it can be run by:

STAMPS_DIR=<path> bitbake -S <recipe>

which will avoid putting the stamps to ${TMPDIR}/stamps.

BTW, break the too long BB_ENV_EXTRAWHITE into several lines.

[YOCTO #1659]
