Downgrade patchelf version from 0.18.0 to 0.17.2 (#295)

Downgrade patchelf version from 0.18.0 to 0.17.2 due to patchelf regression

Patchelf shipped a regression in 0.18.0 and has since yanked the pypi release pointing to
0.17.2 as the most recent version. However, 0.18.0 is still the version shipped in both the apt and yum
repositories, thus we must use pip to install the version we want.
