packaging: lsb_release build and runtime dependency

The lsb_release executable is being run in multiple places, not least in
src/common/util.cc, which calls it via shell in the collect_sys_info() code
path.

This patch addresses this issue on SUSE- and Debian-derivatives, as well
as reinstating the dependency for RHEL/Fedora after it was dropped in
1560057.
