We use `dpkg` 1.19.2 since 23661254e4.
This version dropped pkg_db_reset` in `<dpkg/dpkg_db.h>` which broke compilation with the
following errors:
```
/build/source/osquery/tables/system/linux/deb_packages.cpp: In function 'void osquery::tables::dpkg_setup(pkg_array*)':
/build/source/osquery/tables/system/linux/deb_packages.cpp:83:3: error: 'pkg_array_init_from_db' was not declared in this scope

```
As there's currently no upstream fix, it's better to use an older
version of `dpkg` for now.
