package/hiawatha: bump to version 10.10

package/hiawatha: bump to version 10.10

Changes since 10.9:

- Removed several build options. Functionalities are now always enabled.
- mbed TLS updated to 2.16.3.
- Updated Let's Encrypt script due to changes in the API.
- Bugfix: AlterMode not working correctly.

Diffing the CMakeLists.txt between 10.9 and 10.10 does not show any
build option change that is relevant for us.
