network: dhcp6: re-introduce RapidCommit= setting

Previous implementation of disabling rapid commit was broken, and
dropped by 308d01f3c4decf3240ca0c6c7f91049953df7299.

Let's re-introduce the option in the correct way, as some servers seem
to return borked message when the solicit message contain the rapid
commit option.

Closes #24065.
