cmake: Fix on darwin-arm64

Adds the SystemConfiguration framework to buildInputs unless we're
bootstrapping.

For the bootstrap version, we revert
31f631a142
instead so CMake builds without SystemConfiguration.

+Subject: [PATCH] Disable NAT64 address synthesis on darwin
+
+This intentionally breaks the feature by partially reverting
+https://github.com/curl/curl/commit/31f631a142d855f069242f3e0c643beec25d1b51
+
+This is a stop-gap to get CMake to build without the SystemConfiguration
+framework.
