Revert "Adjust to strncpy removal in linux 7.2-rc1"
There is another repository at
https://github.com/asterisk/dahdi-linux that appears to be compatible to
linux >= 2.6 and we want to in theory merge everything from our repo
into that at some point. strscpy isn't available in such early linux
versions yet, so revert commit b1bc81f8077c5cb52eae7fbd4021bf180159aed7
and add a different fix for building with 7.2-rc1 as next patch.
