tests/leaks.sh: fix intermittent fails on Gentoo (re: 005d38f41)

Browse source 
This applies when ksh is compiled with standard malloc.

Apparently, 1024 iterations is not enough on Gentoo Linux i386, at
least not when running the full test suite. The leak tests fail
intermittently and different tests fail each time, but always with
a leak of exactly 36864 bytes for each failing test. So those
failures are clearly spurious. Doubling the number of iterations
seems to make them go away.
