samples: ftrace: Replace bti assembly with hint for older compiler
When cross-building the arm64 kernel with allmodconfig using GCC 9.4,
the following error occurs on multiple files under samples/ftrace/:
/tmp/ccPC1ODs.s: Assembler messages:
/tmp/ccPC1ODs.s:8: Error: selected processor does not support `bti c'
Fix this issue by replacing `bti c` with `hint 34`, which is compatible
for the older compiler.
