 Extend windows detection in testsuite to recognize MSYS target

 Currently, the detection recognizes the following `uname -s` strings:

  - `CYGWIN_NT-6.3`
  - `MINGW32_NT-6.3`
  - `MINGW64_NT_6.3`

 However, MSYS2 provides an additional target, in which case `uname -s`
 returns a string such as `MSYS_NT-6.3`. In all these cases, the system
 ought to be recognized as being a `windows` os by the testsuite runner.
