Based on Serf trunk commit r1933327.

Add a new patch and update portfile to apply the patch.

• Changes comply with the maintainer guide.
• [n/a] SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• [n/a] The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• [n/a] Exactly one version is added in each modified versions file.

I didn't push it to run the tests though...
