[PATCH 05/13] reftable/reader: inline `reader_seek_internal()`

[Patrick Steinhardt <ps@xxxxxx>]

We have both `reader_seek()` and `reader_seek_internal()`, where the
former function only exists so that we can exit early in case the given
table has no records of the sought-after type.

Merge these two functions into one.
