Pairing script doesn't need downloads

[sorgelig]

xow_MiSTer/xow_pairing.sh

Line 35 in 2aae036

#if [ ! -f "${LINUX_PATH}/xow" ]

lines 35-62 are not required for pairing script. It should check if xow service running or not. Downloading is business of xow_on.sh script.
Currently any attempt to pair resulting to download the binary and then fail because it attempts to replace a running binary.

There is also problem with xow_on.sh script. if ! which "xow" &>/dev/null line doesn't work and script always tries to download even xow is available. At least it's happening when script is started from OSD.

This should be fixed in the latest update to the scripts. Please give it a test and let me know if they are working better. Thanks!
