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.
