[bug#39197] [PATCH core-updates 2/4] gnu: cmake-minimal: Build with a minimal variant of cURL.

[Marius Bakke]

This is necessary to avoid a circular dependency in the next commit.

* gnu/packages/curl.scm (curl-minimal): New public variable.
* gnu/packages/cmake.scm (cmake-minimal)[inputs]: Change from CURL to 
CURL-MINIMAL.
(cmake)[inputs]: Do the opposite.
