crypto: windows: use LPCTSTR for the temp registry buffer

mingw-w64 only defines LPCTCH when UNICODE isn't defined
crypto/defaults.c: In function 'get_windows_regdirs':
crypto/defaults.c:72:5: error: unknown type name 'LPCTCH'; did you mean 'LPTCH'?
   72 |     LPCTCH tempstr = NULL;
      |     ^~~~~~
      |     LPTCH
