(PCP-514) Acceptance - change --version command for Cisco Nexus
(PCP-514) Acceptance - change --version command for Cisco Nexus

Cisco Nexus does not accept commands with an inline env value at the start e.g. 'LIB_PATH=bar /usr/bin/foo'
For the version test, we needed to give the path to vendored Ruby so that pxp-agent would work from a cygwin shell.
Since only Windows requires this, this commit sets PATH only for Windows agents.
