Make combined rmvtransport filters work (#126255)

rmvtransport: make filters always effective

In the `rmvtransport` integration, the three config attributes
`destination`, `lines`, and `time_offset` all act as filters. The
expectation is that if multiple filters are given, all of them take
effect.

However, as a consequence of using `elif` in the loop body, if a
`destination` filter has been configured, then both the `lines` and the
`time_offset` filters are ignored and have no effect.

Replace the `elif` with an `if` clause to allow all filter settings to
work as intended.
