executor: tune few more sysctl's
Faster gc (1 second) is intended to make tests more repeatable.
{"/proc/sys/kernel/keys/gc_delay", "1"},
Huge page overcommit is disabled by default, allowing some
overcommit is intended to give more coverage.
{"/proc/sys/vm/nr_overcommit_hugepages", "4"},
We always want to prefer killing the allocating test process
rather than somebody else (sshd or another random test process).
