Restore the -d flag for destdir when it is supplied. Whilst this is an option

of the standard doclet, many other doclets also use it. For doclets which do not
like it, simply do not provide a destdir attribute to the javadoc tag.

The check for whether destDir is supplied only operated if the standard doclet
is being used (or using javadoc1)
