Revert glibc patch when applicable.

We currently have a dirty fix that looks like this:

# TEMP-FIX for pacman issue
RUN patched_glibc=glibc-linux4-2.33-4-x86_64.pkg.tar.zst \
    && curl -LO "https://raw.githubusercontent.com/sickcodes/Docker-OSX/master/${patched_glibc}" \
    && bsdtar -C / -xvf "${patched_glibc}" || echo "Everything is fine."
# TEMP-FIX for pacman issue

This PR is just a reminder to repeat build tests until it's fixed upstream as noted:

#144

#150

#152

Regular testing until @docker fixes this issue:

git clone https://github.com/sickcodes/Docker-OSX.git
cd Docker-OSX
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
git cherry-pick b79f26a50877673890dabbce2552252d75b4c03e
git commit -m "TEST GLIBC FIX GONE"
docker build -t docker-osx .
