When extracting the emulator script into a separate file, the `matrix.target`
substitution wasn't replaced with an environment variable.

Follow-up to quinn-rs#1950.

`ecn_*` unit tests are failing with any Android API version < v26 with:

```
2024-08-22T14:41:30.636494Z  WARN quinn_udp: sendmsg error: Os { code: 22, kind: InvalidInput, message: "Invalid argument" }, Transmit: { destination: 127.0.0.1:50196, src_ip: None, enc: Some(Ect0), len: 5, segment_size: None }
```

This reverts commit e6f1844.

e6f1844 called `sendmmsg` and `recvmmsg` through `libc::syscall` instead of
`libc::sendmmsg` and `libc::recvmmsg`, thus preventing linking issues on old
Android systems where `libc::sendmmsg` and `libc::recvmmsg` isn't available.

In quinn-rs#1503 (comment) the
decision was made to no longer support these old Android systems (API level 16).

This commit reverts e6f1844. Given that `sendmmsg` support was previously
dropped in ee08826, only the `recvmmsg` calls are reverted.
