Build manylinux2014 wheels instead of manylinux2010

manylinux2010 has been EOL since August 2022; see pypa/manylinux#1281.
In particular, the manylinux2010 image wasn't updated with Python 3.11.
Update scripts/build_dist.sh to use manylinux2014 and drop some CentOS 6
workarounds from scripts/build_manylinux_in_docker.sh.

If someone really wants manylinux2010, we can probably build both, but
none of the popular packages I checked (NumPy, SciPy, cryptography,
charset-normalizer) do this.
