strace/system.c
Denys Vlasenko bcde70adbc Remove extra include directives. No code changes. 
* defs.h: Include <signal.h> unconditionally.
Other files were doing it unconditionally, so no harm done.
* bjm.c: Remove system includes which are already included by defs.h.
* pathtrace.c: Likewise.
* process.c: Likewise.
* signal.c: Likewise.
* strace.c: Likewise.
* stream.c: Likewise.
* syscall.c: Likewise.
* system.c: Likewise.
* util.c: Likewise.
