(#9546) Do not execute com, cmd, exe, or bat files if not on windows

Facter currently only executes com, exe, and bat files if on a windows
system.  It should also exclude these on unix flavored systems since
the interpreter for these "cmd.exe" will not be present.

This also supports the use of pluginsync for external facts where in a
hybrid environment external facts for windows may end up getting syncd
to a unix system.

(Maint) Pin windows gems to match what we ship

The win32-dir gem has a dependency on ffi, which was recently updated to
1.9.3 but does not provide a precompiled version. As a result, the gem will
attempt to compile native extensions, which will fail on our spec boxes
(since the dev kit is purposefully not installed).

This commit pins ffi to 1.9.0, updates win32-dir and windows-pr to the
version that we ship with, and pins each gem to an exact version matching:

(#22622) External output defaults to empty string

 - Previously, if an external fact generated empty output, parse would
   be called with a nil, which cannot have each_line called on it, and
   would cause Facter to crash.  This sets a reasonable default for
   external command output to the empty string

(Maint) Execute test on all agents using beaker's DSL method

Previously, the test was only executing on the first agent host, and it
attempted to run facter directly, which fails on windows when executing
via ssh, because facter is a .bat file, not an executable.

This commit updates the test to run on all agent hosts, and it uses
beaker's built-in DSL method for executing facter, which ultimately
executes:

    cmd /c facter --puppet test_fact1

It also uses beaker's method for passing environment variables to the
command being executed.
