perf annotate: Add init/exit to annotation_options remove default

The annotation__default_options global variable was used to initialize
annotation_options.  Switch to the init/exit pattern as later changes
will give ownership over strings and this will be necessary to avoid
memory leaks.

Committer note:

Fix the GTK2=1 build, hist_entry__gtk_annotate() needs to receive a
'struct annotation_options' pointer.
