   runtests: unset `CURL_MEMDEBUG` for curl requests made to the CI API
   runtests has an automatic feature which detects AppVeyor and Azure CI,
   and communicates runtests test progress and results through the CI API.
   This feature uses the curl tool to send the API requests. It offers the
   `-ac` TFLAGS option to configure an external curl tool for these
   requests, otherwise it uses the freshly built curl tool.
   
   This curl is invoked from the same environment used to invoke the actual
   test curl commands and unit test binaries, thus it has `CURL_MEMDEBUG`
   set and pointing to a test-specific log file.
   
   The issue arises when the curl tool making the API request happens to be
   a debug-enabled one, with the 'TrackMemory' feature enabled. Such curl
   picks up the `CURL_MEMDEBUG` env and dumps it's own, memory tracing
   output into the test's log file. This causes flaky but consistent test
   failures, with bizarre errors, reporting corrupt or unsupported lines,
   and/or just not matching the expected output.
   
   When relying on the freshly built curl (without the `-ac` option) this
   is guaranteed to happen for all debug-enabled builds. As I found out the
   hard way, AppVeyer CI Windows 2012/2016 machines come preinstalled with
   an MSYS2 curl, which has _TrackMemory enabled_, which was explicitly set
   to fix this issue, and caused the very same problem.
   
   To fix, ensure to unset `CURL_MEMDEBUG` before making the API request
   with curl, avoiding this issue with all curl builds. It fixes future
   suprises, and also makes the freshly built curl a viable option in most
   cases, even in debug-enabled builds. (the requirement is to have
   working, cleartext HTTP support; for the AppVeyor API.)
   
   Example fails:
   ```
   ** MEMORY FAILURE
   Not recognized prefix line: SEND sendf.c:391 send(424) = 424
   Not recognized prefix line: RECV sendf.c:459 recv(102400) = 114

   CUSTOMBUILD : FREE error : No memory allocated: MEM C:/projects/curl/lib/url.c:3
   ```
   Notice, current curl no longer emits SEND/RECV log events. The line
   numbers match the source code of curl 7.65.3. The other two examples
   are foreign / corrupt log lines.
   
   The TrackMemory-enabled curl was shipping in MSYS2, and come
   preinstalled on these AppVeyor CI machine, as
   `C:\msys64\usr\bin\curl.exe`:
   - Visual Studio 2015 (Windows Server 2012 R2)
   - Visual Studio 2017 (Windows 2016)
