EventLog: Loop fwrite if necessary during flush
Previously the eventlog flush code would fail if `fwrite` wrote less
than the requested amount. Like all Unix stream I/O operations, however,
`fwrite` isn't guaranteed to write the entire buffer. Here we loop as
long as `fwrite` succeeds in writing anything.
Fixes #11041.
Test Plan: Validate with eventlog
