esp32: Enable workaround for math.gamma(-inf) result.
Without this commit, math.gamma(-float("inf")) returns inf instead of
raising a math domain ValueError. Needed for float/math_domain_special.py
test to pass on esp32.
Root cause is an upstream libm bug, has been reported to ESP-IDF.
This work was funded through GitHub Sponsors.
