Manually tell the compiler that strlcpy exists. The `try-build` function seems
somewhat broken, i.e. any code that I try to pass to it doesn't link because of an
"undefined reference to main" error (and some more quoting issues with newlines being
swalloed).

Because both musl and glibc seemt o support strlcpy nowadays, I decided to just skip the
possibly broken feature-check and hardcode that it exists.
