kernel: throne_tracker: add strscpy/strlcpy compat

Browse Source 
strscpy requires 4.3
strscpy on this usage can be replaced with strncpy + null term.
kernel gives us an option though.
strlcpy is fast af, hotrod fast. It’s just memcpy + null term, so lets go with that.
it got dropped in 6.8 due to risk concerns, so for those, lets use og strscpy.
