[varLib.cff] Round deltas using bankers round as well

Browse Source 
See https://github.com/fonttools/fonttools/pull/2214#issuecomment-790742479

Good news: this reverted the one CFF test that needed its expectation to
change when I started this patchset. Bad news: it introduced a couple other
diffs to the same glyph of the same test, which is consistent with changing
the rounding from otRound to round3.
