additional package requirements

[mayeulk]

In addition to https://github.com/SamuelHassine/zotero-prime/issues/5 I ran into the following errors: debconf: delaying package configuration, since apt-utils is not installed So I suggest adding apt-utils. However, the warning is non-blocking according to: https://github.com/phusion/baseimage-docker/issues/319

Also:

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.
checking for pkg-config... no
pkg-config not found
configure: error: Please reinstall the pkg-config distribution
