trace: Stop compiling in trace_clock unconditionally
Commit 56449f437 "tracing: make the trace clocks available generally", in April 2009, made trace_clock available unconditionally, since CONFIG_X86_DS used it too. Commit faa4602e47 "x86, perf, bts, mm: Delete the never used BTS-ptrace code", in March 2010, removed CONFIG_X86_DS, and now only CONFIG_RING_BUFFER (split out from CONFIG_TRACING for general use) has a dependency on trace_clock. So, only compile in trace_clock with CONFIG_RING_BUFFER or CONFIG_TRACING enabled.
