gnu: gnutls: Update to 3.7.2.

The 3.7 branch, while not considered the "stable" branch upstream, has been
adopted by most major GNU/Linux distributions such as Debian, Arch, openSUSE,
etc.  It has the benefit of receiving all the security fixes.

* gnu/packages/tls.scm (gnutls): Update to 3.7.2.  Remove trailing #t.
[source]: Remove the gnutls-CVE-2021-20231.patch and
gnutls-CVE-2021-20232.patch patches, now incorporated in the source.
* gnu/packages/patches/gnutls-CVE-2021-20231.patch: Delete file.
* gnu/packages/patches/gnutls-CVE-2021-20232.patch: Likewise.
* gnu/local.mk (dist_patch_DATA): De-register them.
