The DFS subfunctions only accept a single $Domain

Specifying the type as an array of strings results in an error when
passing on the parameter to Get-DomainSearcher:

    C:\> Get-DomainDFSShare -Domain test
    Get-DomainSearcher : Cannot process argument transformation on parameter 'Domain'. Cannot convert value to type System.String.
