(#15001) ifconfig regex will optionally match 'addr:'

Newer versions of ifconfig, as found in Fedora 17, have changed the
output format of ifconfig. This change removed the 'addr:' string which
prevents the regex from matching. This patch makes matching 'addr:'
optional.
Test data for net-tools 1.60
(#15001) Add spec examples for ipaddress fact

Without this patch we don't have an example behaviors for the ipaddress
fact.  This patch addresses the problem by adding two examples for the
facts parsing the output of ifconfig.  These examples slightly refactor
the ipaddress fact confined to Linux in order to take advantage of the
stubbed method returning the output of the ifconfig command.

Fixture data for ifconfig output is included for Ubuntu 12.04 and Fedora
17.  The notable difference with Fedora 17 is that Net Tools 1.60
removes the "addr" substring from the interface description.

(#15306) Read /proc/self/status in binary mode

On at least a Joyent SmartMachine (illumos based Solaris) the file
/proc/self/status contains binary data. When read with File.read in Ruby
1.9, this is parsed as UTF-8 which fails with an exception. This patch
instead opens the file in binary mode to avoid the failure.
