lttng-modules: bump to version 2.8.3

LTTng-modules, starting from v2.8, has a mechanism to be built directly
into a Linux kernel image, that is, not as loadable kernel modules. For
this the `CONFIG_LTTNG_CLOCK_PLUGIN_TEST` and `CONFIG_LTTNG` Make
variables were introduced. They need to be explicitly set to `m` here to
build the project as loadable kernel modules.
