Removed duplicate DenierSigner from microsoft-recommended-driver-block-rules

[HotCakeX]

The following DeniedSigner is mentioned twice which isn't supposed to happen.

<DeniedSigner SignerId="ID_SIGNER_ECSIODRV" />

Only one is enough, there is only one signer referencing it

 <Signer ID="ID_SIGNER_ECSIODRV" Name="GlobalSign Primary Object Publishing CA">
      <CertRoot Type="TBS" Value="879269F3F467A6D59641960A62FE9CB419355FF6" />
      <CertPublisher Value="ELITEGROUP COMPUTER SYSTEMS CO" />
      <FileAttribRef RuleID="ID_FILEATTRIB_ECSIODRV" />
    </Signer>

So I just removed the extra DenierSigner, everything checks out now and is valid according to the CI Schema.
