bitbake-layers and devtool both fail to run commands with
meta-external-toolchain included, as it fails to import oe.external. It
turns out that oe_import in base.bbclass is not entirely sufficient to
get the needed modules imported when namespace packages are involved,
and those packages have already been imported. Re-import such packages
after the sys.path change to ensure the new __init__.py files are
parsed, and the new __path__ changes picked up.

This returns immediately with 'UNKNOWN' if the external toolchain isn't
enabled, and also immediately adjusts sys.path regardless of OE_IMPORTS
handling to avoid the over-reliance upon that mechanism.

Since the external toolchain is available at parse time, we can actually grab
the kernel version from the external toolchain sysroot and use that to
determine whether to apply the patch. Do so.

Also provide external-common.bbclass to wrap its inclusion and setup
associated metadata. This will make easier to search sysroots for files
without pulling in the rest of the external toolchain class.
