[PATCH] config/udev: Add sys/sysmacros.h include for major/minor functions for new glibc

[Mart Raudsepp]

Commits d732c36597fa and 84e3b96b5313 added the include to some files, but
missed config/udev.c, where the major and minor functions are used as well.
This should be Linux-only, so we don't need the sys/mkdev.h case here for
Solaris.
