Adding AllowOpen to AllowLlvmSanitizers to avoid having to add AllowOpen in addition when it's only needed for running under the sanitizers.
...
In cases where SAPI users overwrite the default policy instead of extending it, the sandbox will fail with an `openat` violation. This is automatically inherited in the default policy.
The advantage with this implementation is that we don't expose the open* syscalls when not running under the sanitizers.

Update PolicyBuilder to include wrappers for more syscall families that differ between platforms.
...
New wrappers:
- `AllowEpollWait` (`epoll_wait`, `epoll_pwait`, `epoll_pwait2`)
- `AllowInotifyInit` (`inotify_init`, `inotify_init1`)
- `AllowSelect` (`select`, `pselect6`)
- `AllowDup` (`dup`, `dup2`, `dup3`)
- `AllowPipe` (`pipe`, `pipe2`)
- `AllowChmod` (`chmod`, `fchmod`, `fchmodat`)
- `AllowChown` (`chown`, `lchown`, `fchown`, `fchownat`)
- `AllowReadlink` (`readlink`, `readlinkat`)
- `AllowLink` (`link`, `linkat`)
- `AllowSymlink` (`symlink`, `symlinkat`)
- `AllowMkdir` (`mkdir`, `mkdirat`)
- `AllowUtime` (`utime`, `utimes`, `futimens`, `utimensat`)
- `AllowAlarm` (`alarm`, `setitimer`)
- `AllowGetPGIDs` (`getpgid`, `getpgrp`)
- `AllowPoll` (`poll`, `ppoll`)
Updated wrappers:
- `AllowOpen` now includes `creat`. `openat` already grants the ability to create files, and is the designated replacement for `creat` on newer platforms.
- `AllowStat` now includes `fstatfs` and `fstatfs64`. The comment already claimed that these syscalls were included; I believe they were omitted by accident.
- `AllowUnlink` now includes `rmdir`. `unlinkat` already grants the ability to remove empty directories, and is the designated replacement for `rmdir` on newer platforms.
