Unsupported system page size on Asahi Linux

Hi! When I try to run this tool on M1 MacBook with Asahi Linux it fails:

```shell
❯ oha
<jemalloc>: Unsupported system page size
<jemalloc>: Unsupported system page size
memory allocation of 56 bytes failed
fish: Job 1, 'oha' terminated by signal SIGABRT (Abort)
```
