Fixed PR 11336 by using a wait queue to wait on procfs file availability.
* runtime/procfs-probes.c: Removed old kernel 2.6.16 code. Simplified
_spp_lock macros.
(_stp_proc_open_file): If file is busy, use a wait queue to wait on it
being available.
(_stp_proc_release_file): Decrease open count.
* tapset-procfs.cxx (emit_module_init): Updated procfs probe
initialization/shutdown routine names.
(emit_module_exit): Ditto.
