cmake: test integration with old cmake (v3.11.4 2018-03-28)
Tests with old cmake are slow. (no Ninja, no unity, and running slower
than recent versions.)

It also revealed that 3.7.2 2017-01-13 is too old to consume curl via
`find_package()` due to:
```
CMake Error at bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:69 (add_library):
  add_library cannot create ALIAS target "CURL::libcurl" because target
  "CURL::libcurl_shared" is IMPORTED.
Call Stack (most recent call first):
  CMakeLists.txt:48 (find_package)

CMake Error at bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:69 (add_library):
  add_library cannot create ALIAS target "CURL::libcurl" because target
  "CURL::libcurl_shared" is IMPORTED.
Call Stack (most recent call first):
  CMakeLists.txt:49 (find_package)
```
The mitigation for this issue requires 3.11.

Also:
- rename a few existing envs to use the `TEST_` prefix.
- make the `find_package` test provider stage verbose.
- fix issue when consuming with cmake 3.7.2 (all platforms):
  ```
  CMake Error at /home/runner/cmake-3.7.2-Linux-x86_64/share/cmake-3.7/Modules/CMakeFindDependencyMacro.cmake:25 (message):
    Invalid arguments to find_dependency.  VERSION is empty
  Call Stack (most recent call first):
    bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:52 (find_dependency)
    CMakeLists.txt:48 (find_package)
  ```
