lib/oe/package_manager: Don't ignore installation failures in install_complementary

When attempt_only flag is set to True all installation failures are
ignored. Disable attempt_only, that is the default in install function,
to raise error in install_complementary and to prevent do_populate_sdk
task to treat errors as warnings.

[RP: Historically some of our addtional packages were in bad shape and
wouldn't all install. This is no longer the case so we shouldn't need
a hack like this any longer.]
