uic: recognize <legal> tag as an alias for <comment>

That is printed at the top of the file and we've used it for the
copyright inside Qt, so just declare an alias.

[ChangeLog][uic] The Qt UI Compiler now accepts a <legal> XML tag to
indicate the copyright of the UI file and other legal terms of use. The
text of this tag will be emitted in the generated code. This tag is an
alias to <comment>.
