sys-boot/yaboot: bundle e2fsprogs-1.42.13, bug #641560

By default yaboot setup is unusual: it provides it's own
ext2fs headers and links against systems' ext2fs code.

That occasionally breaks when ext2fs.a gets too much out
of sync with expected interface. Pin it to something that
was observed to work by Olivier Néumin.

+Subject: [PATCH] include sys/sysmacros.h as needed
+
+The minor/major/makedev macros are not entirely standard.  glibc has had
+the definitions in sys/sysmacros.h since the start, and wants to move away
+from always defining them implicitly via sys/types.h (as this pollutes the
+namespace in violation of POSIX).  Other C libraries have already dropped
+them.  Since the configure script already checks for this header, use that
+to pull in the header in files that use these macros.
