Remove unneeded sigproc.h includes throughout.

* fhandler.h (fhandler_proc::fill_filebuf): Take a pinfo argument.
* fhandler_proc.cc (fhandler_proc::get_proc_fhandler): Simplify search for
given pid.
(fhandler_proc::readdir): Assume that pid exists if it shows up in the winpid
list.
* fhandler_process.cc (fhandler_process::open): Simplify search for given pid.
Call fill_filebuf with pinfo argument.
(fhandler_process::fill_filebuf): Pass pinfo here and assume that it exists.
* pinfo.h (pinfo::remember): Define differently if sigproc.h is not included.
* dll_init.cc (dll_list::detach): Don't run destructor on exit.
