makedev(3): Use <sys/sysmacros.h> in SYNOPSIS
Defining these functions via <sys/types.h> causes problems for some folk. As noted by Zack Wein: libstdc++ force-enables _GNU_SOURCE, which means people writing in C++ _can't_ avoid these nonstandard macros by using a strict conformance mode. Since glibc has basically always used <sys/sysmacros.h>, update the docs to have people include that instead.
