sysdefs.h: Don't include strings.h anymore.

On some platforms src/xz/suffix.c may need <strings.h> for
strcasecmp() but suffix.c includes the header when it needs it.

Unless there is an old system that otherwise supports enough C99
to build XZ Utils but doesn't have C89/C90-compatible <string.h>,
there should be no need to include <strings.h> in sysdefs.h.
