qa: suppress false positive delete map mismatch errors

Valgrind reports "Mismatched free() / delete / delete []" errors during
OSD startup.

Standard library containers (like std::map) correctly call delete, but
Valgrind falsely interprets this as a call to delete[] because GCC 14
folds the identical aligned delete operators into a single symbol. This
causes Valgrind to flag a mismatch against the non-array allocation.
