jextract build fails on windows

[Sundararajan Athijegannathan]

Hi,

Jorn Vernee reported same issue (and same fix) internally. Not sure why that double quoting is needed on Windows (perhaps shell issues).  I think Jorn Vernee will file a PR.

Thanks,
-Sundar

Subject: jextract build fails on windows

Hi,

After the changes in [1], the jextractapp gradle task fails on Windows
with the error `Error: no value given for --add-options`. While I'm not
exactly sure what is happening here, wrapping the escaped quotes at [2]
in another level of escaping (so they look like `\\\"`) resolves the
issue. After this fix, the task still works successfully on linux (and
presumably mac). I would make a pull request to fix this but I am unsure
if this is the best (or even a valid) solution and due to my OCA
currently being under review, the merging would be blocked anyways.
