You seem to have fixed some cases.

However these cases still fails for me with `wine-9.16-105-g055bddab4f1` (C
source code):
```
execlp("msiexec", "msiexec", "/i", msi_path, "/qn", "MY_PROPERTY="foo bar"",
NULL);
  Got `"foo bar"`, should be `foo bar`

execlp("msiexec", "msiexec", "/i", msi_path, "/qn", "MY_PROPERTY=""""",
NULL);
  Got ``, should be `"`

execlp("msiexec", "msiexec", "/i", msi_path, "/qn", "MY_PROPERTY=""""""",
NULL);
  Got ``, should be `""`

execlp("msiexec", "msiexec", "/i", msi_path, "/qn",
"MY_PROPERTY="{""foo"": [1, 2], ""bar"": {""baz"":
""qux""}}"", NULL);
  No file created, should be `{"foo": [1, 2], "bar": {"baz": "qux"}}`
```
