Revert "gdbus-codegen: emit GUnixFDLists if an arg has type 'h'"

Browse Source 
This reverts commit 4aba03562b, preserving
the new tests but adjusting them to assert that the old behaviour is
restored.

As expected, there were a few projects which broke because of this.
Unfortunately, in one case the breakage crosses a project boundary:
sysprof ships D-Bus introspection XML, which is consumed by mutter and
passed through gdbus-codegen.

Since sysprof cannot add this annotation without breaking its existing
users, a warning is also not appropriate.
