Joe Tsai 6f55309f34 logtail/filch: fix panic in concurrent file access (#18555)
In the event of multiple Filch intances being backed by the same file,
it is possible that concurrent rotateLocked calls occur.
One operation might clear the file,
resulting in another skipping the call to resetReadBuffer,
resulting in a later panic because the read index is invalid.
To at least avoid the panic, always call resetReadBuffer.

Note that the behavior of Filch is undefined when using the same file.
While this avoids the panic, we may still experience data corruption or less.

Fixes #18552
