Subject: [PATCH] fs: remove unnecessary Seek call on log file

We were seeing a (non-fatal) error in our logs:
```
Failed to seek log file to end: seek /proc/1/fd/1: illegal seek
```

Because we open the log file with O_APPEND,
we don't need to manually seek to the end.
As https://pkg.go.dev/os#File.Seek also confirms
that the behavior of `Seek` is not specified
if the file has been opened with O_APPEND,
remove the `Seek` call.
