kprobes/trace: Fix kprobe selftest for gcc 4.6
With gcc 4.6, the self test kprobe function:
kprobe_trace_selftest_target()
is optimized such that kallsyms does not list it. The kprobes
test uses this function to insert a probe and test it. But
it will fail the test if the function is not listed in kallsyms.
Adding a __used annotation keeps the symbol in the kallsyms table.
