Revert %%autosetup patch due to another regression
    
    The repo may be initialized before the macro runs, in which case we
    would fail to create the initial main branch and thus fail on "git
    branch --set-upstream-to=main".  This caused an FTBFS in the edk2
    package:
    
    https://github.com/rpm-software-management/rpm/pull/2121#issuecomment-1202349789
    
    Revert the patch for now as a hotfit and revisit the actual use case
    later upstream, either fixing it properly or reverting there as well.
