pid1: fix the names of AllowedCPUs= and AllowedMemoryNodes=
    
    The original PR was submitted with CPUSetCpus and CPUSetMems, which was later
    changed to AllowedCPUs and AllowedMemmoryNodes everywhere (including the parser
    used by systemd-run), but not in the parser for unit files.
    
    Since we already released -rc1, let's keep support for the old names. I think
    we can remove it in a release or two if anyone remembers to do that.
    
    Fixes #14126. Follow-up for 047f5d63d7a1ab75073f8485e2f9b550d25b0772.
