* gnu/packages/curl.scm (curl-7.66.0): Use patch.
* gnu/packages/patches/libcurl-use-ssl-cert-env.patch: New file.

This fixes the SSL errors occuring when trying to use rust:cargo's
download functionality.

As an additional advantage, this will probably allow removing some
package-specific work-arounds that have already been made. I have
found such work-arounds in cmake and kodi, but am not familiar enough
with either to confidently remove them.

The commit message forgot to mention the changed patches.  However I
opted to remove them, as the Kodi and CMake patches are harmless even
with your patch, but will encourage you to fix them regardless.  ;-)

Also added the new patch to gnu/local.mk and adjusted indentation of the
cURL comments.

Pushed as a76a343082d61d5303b61a9e4cbde4ab8515a1e7, thanks!
