[OE-core] [PATCH 1/1] sanity.bbclass: check for validity of TMPDIR

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

TMPDIR must be an absolute path, otherwise, the build will fail.
Special characters in TMPDIR will also cause build failures.

This patch enables checking for the validity of TMPDIR.
