watch: fix uninitialized variable

When building with meson, Jenkins reported the following warning:

```
../watch.cpp: In lambda function:
../watch.cpp:74:30: error: ‘buffer’ may be used uninitialized [-Werror=maybe-uninitialized]
   74 |             int length = read(fd, buffer.data(), buffer.size());
```
