Strip cross-platform pvrecorder native binaries from Windows packaging

@github/copilot now pulls in @picovoice/pvrecorder-node, which ships
pv_recorder.node binaries for mac, linux, and windows under lib/.
rcedit.exe cannot process the non-Windows variants and aborts the
Windows packaging step. Strip lib/mac/** and lib/linux/** from the
build via .moduleignore; keep lib/windows/** intact.
