Subject: [PATCH] extlinux: pull in sys/sysmacros.h for major/minor/makedev

These functions are defined in sys/sysmacros.h, so add the include to
main.c.  This is already handled correctly in mountinfo.c.  Otherwise
we get build failures like:

main.o: In function 'find_device_sysfs':
extlinux/main.c:1131: undefined reference to 'minor'

Upstream-Status: Pending

The first part wasn't enough in OE build, I had to add the same for syslinuxext.c.
