Add openSUSE support

[ghost]

While openSUSE is also an RPM distro it is not completely compatible with the RedHat distros. So I had to make this spec file based on the RH one in order for it to work on openSUSE and OBS.

Some changes:

• Uses /usr/lib/systemd/system to store the service because SUSE doesn't allow /etc/systemd/system to be used by packages
• The package for go is called go on openSUSE and not golang. Similar issue with shadow.
• Change license name to the one SUSE allows. You should use identifier in https://spdx.org/licenses/
• Because OBS build environment has no internet connectivity, you have to add another source with all of go's dependencies and make it the $GOPATH
• I changed the file mask for systemd service from 0755 to 0644
• Doesn't use the ./build shell script because RPM Lint recommends I build PIE executable and ./build script doesn't take arguments to go build.

The openSUSE repo I created is @ https://build.opensuse.org/package/show/home:ranyy/yggdrasil

Thanks for this - looks good! Is it ready to merge?

Yes, it's ready to merge. You just need the go.txz to be the $GOPATH that contains everything that go needs to download from the internet because the build environment has no internet. I'm not sure if you need this, but you will need it if you're using SUSE's OBS.

I don't think there is anything to improve besides apparmor support and maybe some man pages if they're available. All warnings are resolved and I don't have any problems with it.

I added the needed go.txz file to this branch.

I think this should be closed now. https://github.com/rany2/yggdrasil-opensuse-pkg does this better without the need to bundle GOPATH or anything of the sort (because the build environment already has internet connection).

The modified spec that's needed for openSUSE needs to be merged here and that's all.

Edit: it's not compatible with Fedora or the other Red Hat ones because it's a different distro and everything
