Fix EOL removals from conditionals in the table latex templates

This business of conditionals and EOLs is a can of worms.

I spend time on this but it is expected to completely remove these
conditionals from the templates and use \sphinxtoprule, \sphinxmidrule,
\sphinxbottomrule mark-up rather.

MEMO: I saw an \hline in a tabulary in tests which does not come from
template but from table body, so this should be tracked and modified
where it originates (presumably sphinx/writes/latex.py).
