Chen Qi 9a9124e50c eSDK.py: unset BBPATH and BUILDDIR to avoid eSDK failure
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.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
