dpkg-native: fix deb-based rootfs construction failure on Fedora 16
Backport a fix from 1.16.x upstream to use fd instead of stream-based
I/O in dpkg-deb, which avoids the use of fflush() on an input stream
(the behaviour of which is undefined by POSIX, and appears to have
changed in the version of glibc introduced in Fedora 16 and presumably
other systems).
Fixes [YOCTO #1858].
