Bug#842292: libnss3: re-enable SSLKEYLOGFILE support

[Evgeny Kapun]

Package: libnss3
Version: 2:3.26-2
Severity: wishlist

In previous versions of libnss, it was possible to use SSLKEYLOGFILE environment variable to save session keys to a file. Since version 3.24, this is disabled by default at compile time [1].

I think that SSLKEYLOGFILE support should be enabled for Debian builds of libnss, since otherwise users who need this functionality have to make their own builds of libnss.
