I found the root cause, it is because busybox and libc6 depends on each other,
busybox' elf files depends on libc6, and libc6's postin depends on busybox'
/bin/sh, the do_rootfs works well is because dnf-native has set
RPM_NO_CHROOT_FOR_SCRIPTS=1, but it would be failed for a fresh rootfs.

In rpm 4.20.1, it let the installed files' Requires win, so it installed busybox
firstly, but in rpm 6.0.1, it let the postin's Requires win since postin would
run immediately after the files are installed, this does make sense, so it
installed busybox (which provides /bin/sh required by libc6' postin) firstly,
then we got the errors. I couldn't find which commit made this change because
a lot of files and functions are refactored during 4.20.1 and 6.0.0 (not .1),
I also tried bisect, but failed because a lot of do_patch or
do_configure/do_compile failures for each build.

For libc6's the postin is:

#!/bin/sh
if [ x"$D" = "x" ]; then
     if [ -x /sbin/ldconfig ]; then /sbin/ldconfig ; fi
fi

This doesn't make sense for lib6 since there is no /bin/sh or ldconfig when
libc6 is not ready, so we can just remove libc6's postin to fix the problem.

I will send a V4 for it if no objections.
