Require polarssl >= 1.2.10 for polarssl-builds, which fixes CVE-2013-5915.

PolarSSL 1.2.9 fixes a possible timing attack in PolarSSL's RSA-CRT
implementation. See CVE-2013-5915 for details. This commit bumps the
minimum polarssl version required by configure.ac to 1.2.10, because 1.2.9
also introduced a memory leak, which is fixed in 1.2.10.
