Work around a problem arising from the update to OpenSSL 1.0.2f, based on the
following upstream commit:
https://github.com/noxxi/p5-io-socket-ssl/commit/6e23ee4a433f83f1065bd2467255eba5ee9b1ddd
Attempting to update to IO-Socket-SSL-2.023, which includes this commit,
caused other test failures. See:
https://lists.gnu.org/archive/html/guix-devel/2016-01/msg01032.html
Description from the upstream commit:
OpenSSL 1.0.2f changed the behavior of SSL shutdown in case the TLS connection
was not fully established (commit: f73c737c7ac908c5d6407c419769123392a3b0a9).
This somehow resulted in Net::SSLeay::shutdown returning 0 (i.e. keep trying)
which caused an endless loop. It will now ignore this result in case the TLS
connection was not yet established and consider the TLS connection closed
instead.
