Update to 1.3.8 (security fix).

Changes for APR 1.3.8

  *) SECURITY: CVE-2009-2412 (cve.mitre.org)
     Fix overflow in pools and rmm, where size alignment was taking place.
     [Matt Lewis <mattlewis@google.com>, Sander Striker]

  *) Make sure that "make check" is used in the RPM spec file, consistent
     with apr-util. [Graham Leggett]

  *) Pass default environment to testflock, testoc and testpipe children,
     so that tests run when APR is compiled with Intel C Compiler.
     [Bojan Smojver]
