Issues when adding --vst3validator option on Linux #152
Description
When running pluginval with --vst3validator on Linux it fails to load the plugin in to the validator. The following command im running
./pluginval --strictness-level 10 --skip-gui-tests --validate-in-process --vst3validator ~/development/audio/build/bin/Release/validator ~/.vst3/MyPlugin.vst3
Which will add this section when --vst3validator has been added as an option

So it seems the validator expects the bundle dir (.vst3) as the argument to the validator binary itself. This error seems to happen internally in Juce due to calling this function when setting up the audio host.
static File getDLLFileFromBundle (const String& bundlePath)
{
#if JUCE_LINUX || JUCE_BSD
const auto machineName = []() -> String
{
struct utsname unameData;
const auto res = uname (&unameData);
if (res != 0)
return {};
return unameData.machine;
}();
const File file { bundlePath };
return file.getChildFile ("Contents")
.getChildFile (machineName + "-linux")
.getChildFile (file.getFileNameWithoutExtension() + ".so");
#else
return File { bundlePath };
#endif
}
which in the end will populate the desc.fileOrIdentifier in VST3Validator class in Pluginval to use the .so file as the file to load in to the validator instead of the plugin bundle dir (MyPlugin.vst3). Using --vst3validator on Windows or Mac does not cause this issue and works fine there.
Using desc.fileOrIdentifier when running Linux does not seems to be a feasible solution in pluginval when using --vst3validator option since it will return the .so instead of the .vst3 bundle.
