2aab11fa5a Fix the temporary directory search algorithm for unix so that it fails 
gracefully even if all candidate directories are inaccessible.  This fixes
a bug that was introduced by check-in [9b8fec60d8e].

enabled at all times.  In this way, applications can enable extension loading
for the C interface without having to expose that capability to the SQL.
