[Actions] Build Packager on Linux with its dependencies (32- and 64-bit) (#351)

* Install all necessary packages to build OPKG repository and enabled building of Packager

* Use the development template to test

* Check the config paths of PKG

* Add a PKG config path to the opkg lib directly

* No need for brackets as PKG_CONFIG_PATH is an env variable and not runner's one

* Try adding the path to a global env variable of the runner

* Fix the path to point to the pkg file and not just the whole lib

* Update the prefix so that opkg ends up in the default path for cmake to find it

* Update the env variable with a new path as well

* Try the default path instead..

* Add more debugging info..

* Fix the includedir in the libopkg.pc

* Try to locate the headers

* Ls more paths to find the real install place

* Try with the most default settings

* Try to copy the headers and put them in the correct spot

* Use the GitHub workspace variable to be more robust for any future changes

* Make sure to build libopkg for 32 bit in 32 bit builds

* Make sure to install 32 bit packages for the 32 bit build of libopkg

* Update the PKG_CONFIG_PATH to include the i386 linux packages for 32 bit libopkg build

* Simplify the formatting

* Use the template for master after the testing is done
