esx: pass 'long' to curl_easy_setopt when needed

esx: pass 'long' to curl_easy_setopt when needed

The include header got its type checks fixed in curl 8.14:
https://github.com/curl/curl/commit/79b4e56b3f30dc1ac28a81128a07d27338e5219e
https://github.com/curl/curl/pull/17143

This causes a warning on rawhide with clang:
../src/esx/esx_vi.c:318:5: error: call to '_curl_easy_setopt_err_long'
declared with 'warning' attribute: curl_easy_setopt expects a long
argument [-Werror,-Wattribute-warning]
  318 |     curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1);
      |     ^
