The package name changed from Cheetah3 to ct3[1], so we didn't get any
upgrade notices from AUH. Update the PYPI_PACKAGE, and upgrade to the
latest release.
Remove the RDEPENDS on legacy-cgi, this is no longer needed[2].
License-Update: Copyright years updated.

[2] cheetah3 02a4076 ("Fix(webInput): Use `parse_qs` instead of `cgi`")
