testexport.bbclass: Add support for testexport-tarball

Add support to export the SDK tarball needed when a test
system doesn't have the required software to perform runtime
tests.

The support is when exporting the test and when running
the test on a remote system. The user of this feature just
need to set TEST_EXPORT_SDK_ENABLED to "1" and declare
the sdk packages in TEST_EXPORT_SDK_PACKAGES.
