onclite: wifi: Enhance move_wifi_data.sh to copy required files

Commit I3b8c050878b0df3cc1cfcba27b7716ab0a9cde31 moves all the
files from /data/misc/wifi to /data/vendor/wifi for OTA update.

Not all files need to be moved, e.g. moving WifiConfigStore.xml
makes saved networks lost.

So use copy instead of move for required files only:
- p2p_supplicant.conf: persistent p2p networks
- hostapd.accept: mac whitelist (if present)
- hostapd.deny: mac blacklist (if present)
