dirs: fix out-of-bounds access in Py3 The hack for mutating Python's variable-length integers that was ported to py3 in (dirs: port PyInt code to work on Python 3, 2016-10-08) was reading from ob_digit[1] instead of ob_digit[0] for some reason. Space for ob_digit[1] would only be allocated for integers larger than 30 bits, so we ended up writing to unallocated memory. Also, we would write an integer that's 2^30 times too large, so we would never free these integers. Found by AddressSanitizer. Differential Revision: https://phab.mercurial-scm.org/D7597
