[OE-core] [PATCH] oeqa/core/loader: Make _built_modules_dict() support packages correctly

[Peter Kjellerstedt]

For test modules in a package, e.g., oelib.license, running
`oe-selftest -r oelib.license` or `oe-selftest -r
oelib.license.TestSimpleCombinations` would fail with a message that
the specified test cases could not be found. This was due to the
parsing in _built_modules_dict(), which failed to distinguish between
<package>.<module>.<class> and <module>.<class>.<testcase> and treated
both cases as the latter.
