Makefile: use libsqlite3 build when possible

Dynamically link sqlite3 when installed, the main motivation is that we
reduce the podman binary size with that. I see about 3.2 MB savings.

But also dynamically linking it means if there a vulnerabilities only
the sqlite3 distro package needs updating and we don't have to make a
new podman release with the vendored update.
