build-sys: treat format errors as fatal (#4910)
We currently don't expect any warnings about format strings, on any architecture (#4612 removed the last few warnings). Turn those warnings into errors in the future. As requested by Martin Pitt. gcc documentation says that -Wformat=2 includes -Wformat-security and -Wformat-nonliteral so don't include them explicitly.
