tst_QPluginLoader: make the plugin tests work on HarmonyOS

The test resolved its helper plugins through QFINDTESTDATA("bin/..."),
a build-tree layout that does not exist inside a HAP, so every row that
opens or loads theplugin failed: 83 of 89 functions. Resolve them from
the library paths instead, where HarmonyOS keeps the flat libs dir of
the package, and declare the runtime-loaded plugins as extra libs so
they are packaged in the first place - they are dlopen'ed by name, not
linked, so nothing else pulls them in.

relativePath() and absolutePath() need no library-path setup, like on
Android, but the plugin file name carries no architecture suffix and the
absolute path has to be resolved before the paths are cleared, so both
get their own branch.

Result on device: 89 passed, 1 skipped (was 6 passed, 83 failed),
identical on a tablet and a 2in1.
