KWSys: Remove "copyPermissions" parameters

The CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory
methods should always copy permissions.  The special cases in which a
caller would pass copyPermissions=false should be handled at the call
site.  The parameter needlessly complicates the interface and semantics
of these methods.
