unset NIX_HARDENING_ENABLE in fast build mode

Browse source 
`NIX_HARDENING_ENABLE` causes `_FORTIFY_SOURCE` to be defined.
This isn't compatible with `-O0`, and the compiler will happily remind
us about it at every call, spamming the terminal with warnings and stack
traces.

We don't really care hardening in that case, so just disable it if we
pass `OPTIMIZE=0`.
