blkin: link against lttng-ust-fork

Tracing with LTTng doesn't work if an application clone()s other
threads. This is an LTTng-related issue and the fix is LD_PRELOAD'ing
liblttng-ust-fork, or linking against it.
We don't have this issue with "regular" tracepoints (see WITH_LTTNG)
because the tracepoints are loaded using dlopen() at runtime by each
Ceph process.
