Subject: [PATCH] Allow getrandom, rseq, and prctl for glibc malloc

glibc uses getrandom in malloc, rseq, and prctl in various other
places, allow these syscalls in seccomp filter.

```
export GLIBC_TUNABLES=glibc.mem.decorate_maps=1
make check
```

Remove the dumb prctl allow rule as for glibc malloc the prctl PR_SET_VMA
with flag PR_SET_VMA_ANON_NAME is already allowed
