kselftest/arm64: mte: use string literal for printf-style functions

Browse Source 
Using pointers for the format specifier strings in printf-style
functions can create potential security problems, as the number of
arguments to be parsed could vary from call to call. Most compilers
consequently warn about those:
"format not a string literal and no format arguments [-Wformat-security]"

If we only want to print a constant string, we can just use a fixed "%s"
format instead, and pass the string as an argument.
