Make both versions of _cairo_lround consistent again

Browse source 
Commit c0008242b0 made cairo use libm's lround instead of its own _cairo_lround
by default. However, since commit ce58f874 from 2006, _cairo_lround does
arithmetic rounding instead of away-from-zero rounding (before said commit, it
was using baker's rounding).

So to make the rounding of _cairo_lround be independent from
DISABLE_SOME_FLOATING_POINT, we have to use another function. Turns out that
_cairo_round already does the same thing that _cairo_lround does. Their only
difference is the return type.
