oetest.py: Add install/uninstall functionality for DUTs

Add the functionality to install/unistall packages in the
DUTs without the use of the package manager. This is possible
with the extraction introduced in package manager class.

testimage and testexport bbclasses has been modified in order
to support this new feature.
