cpython: Enable LTO on all builds as it doesn't break reproducibility
LTO allows us to optimise the binaries we are shipping a bit further
than just with the regular -Ox and other compiler flags. It also is
deterministic and doesn't harm our reproducibility efforts while
providing us with up to 10% performance gain (and sometimes slightly
slower). See the table below for a comparsion of this version with the
Python 3.9 build that sets -fno-semantic-interposition.
