[PATCH] [mom]: Simplify `pdfhref` calls.

Hi Peter & Deri,

I noticed that the `-E` argument to a `.pdfhref L` call doesn't seem to
do anything.  I compared before-and-after, and while the PDF checksums
change, the file sizes do not.  I assume there is a shifty data
structure (like a hash table) or an embedded date stamp in the PDF that
changes.  I'd have more to report, but _pdfmom_ doesn't support groff's
`-Z` option.

Hyperlinks of various types, both internal (whether from tables of
contents or within body text) and external still work fine, and appear
to have correct link text.

Ok to push?

Regards,
Branden
