tracing: remove unnecessary trace_trigger ifdef

Browse Source 
The trace_trigger command line option introduced by
commit a01fdc897f ("tracing: Add trace_trigger kernel command line option")
doesn't need to depend on the CONFIG_HIST_TRIGGERS kernel config option.

This code doesn't depend on the histogram code, and the run-time
selection of triggers is usable without CONFIG_HIST_TRIGGERS.
