[OE-core] [PATCH 1/1] eSDK.py: unset BBPATH and BUILDDIR to avoid eSDK failure

[Chen Qi]

When executing eSDK test case, the following error appears.

  WARNING: attempting to use the extensible SDK in an environment
  	   set up to run bitbake - this may lead to unexpected
	   results. Please source this script in a new shell session
	   instead.

  FileExistsError: [Errno 17] File exists: '/.../tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/selftest-esdk-fcuyzsqu/tmp/sysroots/x86_64/bin/pigz' -> '/.../tmp/hosttools/pigz'

So unset these two vars to avoid messing things up.
