Add missing Python build deps and fix apt-get name overrides

Adds curl, ncurses-devel, xz (tool), libxml2-devel, and xmlsec1-devel to
SYSTEM_PACKAGES to cover the full pyenv/CPython build dependency set.

Also adds apt-get overrides for all Fedora-named Python build packages
(bzip2-devel → libbz2-dev, openssl-devel → libssl-dev, etc.) so they
resolve to the correct Debian/Ubuntu package names at install time.
Adds corresponding brew overrides for the new packages.
