Test failures on aarch64 after merging PR 8851

[niedbalski]

Description

After merging PR [#8851](#8851), the following tests were re-enabled for the aarch64 actuated job:

• -DFLB_WITHOUT_flb-it-utils=1 -DFLB_WITHOUT_flb-it-pack=1
• Without any omit option.

However, these tests are now failing on the master branch.

Affected Tests and Errors

1. Proxy URL Test Failure

   Test test_write_str_buffer_overrun...           [ OK ]
   Error: oxy_url_split...                         [2024/12/03 09:26:23] [error] only HTTP proxy is supported.
   [ OK ]
   

   Error Details:
   The oxy_url_split test is emitting an error:

   [2024/12/03 09:26:23] [error] only HTTP proxy is supported.
   

2. Quoted String Splitting Test Failures

   Test test_flb_utils_split...                    [ OK ]
   Test test_flb_utils_split_quoted...             [ OK ]
   Error: st_flb_utils_split_quoted_errors...      [2024/12/03 09:26:23] [error] Parsing failed: aa "unbalanced quotes should fail
   Error: [2024/12/03 09:26:23] [error] Parsing failed: aa 'unbalanced quotes should fail
   

   Error Details:

   • st_flb_utils_split_quoted_errors fails when processing invalid quoted strings.
   • The errors indicate unbalanced quotes should cause a failure but instead generate parsing error logs.

Steps to Reproduce

1. Checkout the master branch post-merge of PR [#8851](cmake: fix UNICODE-escaped characters on aarch64 #8851).
2. Enable the tests by omitting the -DFLB_WITHOUT_flb-it-utils=1 -DFLB_WITHOUT_flb-it-pack=1 options.
3. Run the tests on an aarch64 environment.
4. Observe failures in the oxy_url_split and st_flb_utils_split_quoted_errors tests.

Expected Behavior

The tests should pass on the aarch64 platform without errors when re-enabled.
