Forcing the installation of zlib, pcfe, libcurl, and pkg-config for `dockerize()`

[chainsawriot]

zlib, pcfe, libcurl are actually sysreqs for building R. https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Essential-programs-and-libraries

But in the case of not building R (e.g. using Rocker), those sysreqs are not always installed.

And many bioc packages have tacit sysreqs to these.
