    meson: Enable -Wformat-security
    
    This warning is disabled by default at warning level 1.
    
    Multiple distros are building Tracker with -Werror=format-security and
    discovering regressions, we have had reports from Debian, Fedora and
    NixOS so far, so let's enable it by default.
