radsecproxy: update to 1.6.2

radsecproxy: update to 1.6.2

Since my previous post a similar issue was discovered for DTLS and 1.6.2
was released. CVE numbers were also assigned for these two
vulnerabilities:

CVE-2012-4523 refers to the TLS issue, fixed in radsecproxy 1.6.1
CVE-2012-4566 refers to the DTLS issue, fixed in radsecproxy 1.6.2

So it would be good to bump to 1.6.2, applying this patch on top of
r34484.
