AppStream metadata is not found if named %{id}.metainfo.xml

[ProjectSynchro]

I get a warning when building if AppStream metadata is named %{id}.metainfo.xml instead of %{id}.appdata.xml.

[appimage/stderr] WARNING: AppStream upstream metadata is missing, please consider creating it
[appimage/stderr]          in usr/share/metainfo/org.naev.naev.appdata.xml
[appimage/stderr]          Please see https://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html#sect-Quickstart-DesktopApps
[appimage/stderr]          for more information or use the generator at http://output.jsbin.com/qoqukof.

The page that message links to even suggests the use of %{id}.metainfo.xml

Please try whether #121 resolves this. Thanks!

The code looks good, but I am sadly not able to test it at the moment. Can someone else confirm that the new PR works as intended? Thanks!
