We have seen CI being flaky due to a sporatic
openatsyscall. Turns out (g)libc can try to open/proc/sys/vm/overcommit_memoryduring a call tofree().This PRs makes
openatreturnEACCESrather than trap.An alternative solution I tried is to "prime" malloc/free before applying the seccompfilter, but that didn't work.
Closes #175
