Add kprobe user probe semaphore handling.
Adds stap_kprobe_process_found and stap_kprobe_mmap_found handlers
and then the task_finder uses those to set the semaphore values.
The probe adds user_path and user_lib which are used by the
task_finder to decide what object to sniff.
* sdt.h (STAP_SEMAPHORE): Also define for kprobes.
* tapsets.cxx (dwarf_derived_probe): Add user_path and user_lib.
(dwarf_derived_probe::join_group): Enable task finder for kprobes.
(dwarf_derived_probe::dwarf_derived_probe): Set user_path and
user_lib.
(dwarf_derived_probe_group::emit_module_decls): Emit
stap_kprobe_mmap_found, sdt_sem_offset, sdt_sem_address, pathname,
and finder declarations. Emit stap_kprobe_process_found and
stap_kprobe_mmap_found.
(dwarf_derived_probe_group::emit_module_init): Setup task finder.
(sdt_query::convert_location): Remove TOK_LIBRARY token.
(dwarf_builder::build): Set user_path and user_lib.
(kprobe_derived_probe): Add path and library.
(kprobe_builder::build): Get process and library params
