Tianhao Chai c2192cfa98 mangohud support: getLibraryString should return absolute path when possible ...

Some distros ship MangoHub vulkan layer json with bare shared object name
instead of an absolute path. This breaks environment config as
`MinecraftInstance::createLaunchEnvironment()` seems to require absolute
path of `libMangoHud.so`.

Since we already have `MangoHud::findLibrary()` lying around, use that to
figure out where `libMangoHud.so` really is. In case of a platform that
doesn't support `dlopen()`, fallback to old behavior and return the path
verbatim as it is recorded in vk layer json.
