[Buildroot] [git commit branch/2025.02.x] package/cjson: security bump to version 1.7.19

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=e6423ca55045d27c85b4cdce279bf5415e968ad9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.02.x

Fixes the following security issue:

CVE-2025-57052: cJSON 1.5.0 through 1.7.18 allows out-of-bounds access via
the decode_array_index_from_pointer function in cJSON_Utils.c, allowing
remote attackers to bypass array bounds checking and access restricted data
via malformed JSON pointer strings containing alphanumeric characters
