Description of problem:
I'm trying to build a couple of packages in Rawhide today that use pdflatex to build documentation.  The pdflatex binary fails to start (in mock) due to unsatisfied dependencies:

$ ldd /usr/bin/pdflatex

The 3 missing libraries all belong to nss.  Sure enough, nss is not required by the texlive-pdftex package:

Version-Release number of selected component (if applicable):
texlive-pdftex-20200327-22.fc34.x86_64

How reproducible:
Always

Steps to Reproduce:
1. mock -r fedora-rawhide-x86_64 --install texlive-pdftex
2. mock -r fedora-rawhide-x86_64 --shell
3. pdflatex dummy.tex

Actual results:
Pdflatex fails to start due to missing nss libraries.

Expected results:
Pdflatex should have all of its dependencies satisfied so it can run.
