[FIX] account: fix reconcile rule percentage calculation

In https://github.com/odoo/odoo/pull/52529/commits/078a3a0f760ff24d02070a343f28d2249a8b5ba7#diff-c217a13a40a3cc27dc516b899793abecfac8cab9a42fed407d4776bcbc9de9a8R812
the way the percentage is calculated is changed.
This implies that a reconciliation rule allowing a 90% matching amount will not allow to reconcile
a 90$ bank statement with a 100$ invoice (as it will calculate the % as 88.89%, not meeting the required 90 %)

After cited commit:
invoice 200, bank statement 180:
(|-180| - |20|) / |-180| * 100 = 88.89%
invoice 200, bank statement 220:
(|-220| - |-20|) / |-220| * 100 = 90.91%
credit note 200, bank statement -180:
(|180| - |-20|) / |180| * 100 = 88.89%
credit note 200, bank statement -220:
(|220| - |20|) / |220| * 100 = 90.91%

Now:
invoice 200, bank statement 180:
100 - |20| / |(-180 - 20)| * 100 = 90%
invoice 200, bank statement 220:
100 - |-20| / |(-220 - -20)| * 100 = 90%
credit note 200, bank statement -180:
100 - |-20| / |(180 - -20)| * 100 = 90%
credit note 200, bank statement -220:
100 - |20| / |(220 - 20)| * 100 = 90%
