Description of problem:

When dnf gets upgraded on rawhide, either directly or as a dependency, subsequent dnf invocations fail with

/usr/libexec/system-python: relocation error: /lib64/libpython3.6m.so.1.0: symbol getrandom, version GLIBC_2.25 not defined in file libc.so.6 with link time reference

Version-Release number of selected component (if applicable):

dnf-2.0.0-0.rc1.4.fc26.noarch -> dnf-2.0.0-2.fc26.noarch

How reproducible:

Deterministic.

Steps to Reproduce:
1. docker run --rm -ti fedora:rawhide bash
2. In the container: dnf upgrade -y dnf
   Or something like dnf install -y rpm-build which for some reason upgrades dnf as well.
3. In the container: dnf list

Actual results:

/usr/libexec/system-python: relocation error: /lib64/libpython3.6m.so.1.0: symbol getrandom, version GLIBC_2.25 not defined in file libc.so.6 with link time reference

Expected results:

No error.
