runtime: remove linkname from memhash{32,64} functions
Remove linkname directives that are no longer necessary given
parquet-go/parquet-go#142 removes the dependency on the `memhash{32,64}`
functions.
This change also removes references to segmentio/parquet-go since that
repository was archived in favor of parquet-go/parquet-go.
Updates #67401
