DocBook/JATS reader: don't export surrounding space from inline elements.

Previously we would export leading and trailing space inside
elements like emphasis or ulink so they appeared outside the
resulting pandoc Inline (Emph or Link). This is not really
motivated; DocBook and XML in general treats leading and trailing
whitespace in this context as significant.

These spaces may casue problems for some output formats, e.g.
asciidoc, but these issues should be addressed in the
corresponding writers, as they are in the Markdown writer,
using Text.Pandoc.Writers.Shared.delimited.

Closes #11398.
