Currently the substitutions fail to match if the path contains re

If we run in tmpdir, and run a bitbake -e after wiping tmpdir,
EXTERNAL_TOOLCHAIN_SYSROOT will be 'UNKNOWN' rather than the correct path, due
to PWD not existing when we try to extract the sysroot path.

oe.path.check_output was returning a bytes, not an str. Switch to bb.process
to resolve issues with python3.

Also provide external-common.bbclass to wrap its inclusion and setup

without pulling in the rest of the external toolchain class.
