These rtl_hash* functions appear to never have been exported from sal

They were introduced with 9399c662f36c385b0c705eb34e636a9aec450282 "initial
import" without any trace of being exported DLLPUBLIC-style, and were probably
included in error in the initial sal/util/sal.map when that was introduced in
92b0714c409bd3cffcefd338371ee000fa1b5805 "new".

That means the functions themselves can be moved from extern "C" to an unnamed
namespace (and the resulting loplugin:salbool warnings be fixed).
