Remove the global derived_probe->semaphore map
Instead just make the semaphore address a member of derived_probe.
* session.h (systemtap_session): Remove the map sdt_semaphore_addr.
* elaborate.h (derived_probe): Add sdt_semaphore_addr directly.
* tapsets.cxx (sdt_query::record_semaphore): Write the addr directly.
(uprobe_derived_probe_group::emit_module_decls): Read it directly.
* tapset-utrace.cxx (utrace_derived_probe_group::emit_probe_decl): Ditto
