    [rpm] Handle the tilde separator in versioning

    We need correctly handle the tidle separator in RPM versioning [1]:
    eg:
       rpmdev-vercmp 1:8.0.0~b3 1:8.0.0
           1:8.0.0~b3 < 1:8.0.0
           1:8.0.1~b3 > 1:8.0.0
           1:8.0.0~b3 < 1:8.0.1~c1
           1:8.0.0~b3 > 1:8.0.0~a1
