[xep-support] Superscript/subscript and lineheight

Use line-height-shift-adjustment="disregard-shifts" attribute
on the fo:block. It is inheritable, so placing it on the fo:root
will effectively bring XEP's treatment of superscripts/subscripts
to FOP's.

By the XSL spec [7.15.5], line-height-shift-adjustment defaults 
to "consider-shifts". I am afraid FOP is not conformant here.
