only enable -Werror in CI

Enabling -Werror by default sucks for everyone who isn't maintaining
CDBA. By all means we should enable it in CI, but not for users and
not for folks packaging it in distros.

Remove it from the flags in meson.build, and use mesons built in option
to enable it only in CI.
