Upgrade cl-hunchentoot to version 1.3.0

[Tim Lee]

In Guix, the latest version of Hunchentoot is 1.2.38 (released on
2017-12-03). There is a new upstream version 1.3.0 (released on
2021-05-07). Can someone upgrade cl-hunchentoot? I am not familiar with
the Guix packaging process, but it appears that the following patch is
sufficient:
