    patch 9.2.0928: MinGW: tests hang when Vim is built with coverage enabled
    
    Problem:  When building with MinGW and COVERAGE=yes the tests hang: a
              command started from Vim never returns, although the child
              process has already exited.
    Solution: Do not build vimrun.exe with coverage instrumentation.
    
    fixes:  #20976
    closes: #20991
