Update to 2.1.1 release
    
    This commit updates the tpm2-tools package to version 2.1.1. It also does
    some cleanups such as changing the prefixes to tpm2-tools that is the new
    name for the upstream project repository. Since this matches the pkg name
    the global pkg_prefix can be removed.
    
    It also removes the downstream patches since these are already present in
    the latest upstream release.
    
    resolves: rhbz#1504438
