ftrace: kprobe: uprobe: Show u8/u16/u32/u64 types in decimal
Change kprobe/uprobe-tracer to show the arguments type-casted
with u8/u16/u32/u64 in decimal digits instead of hexadecimal.
To minimize compatibility issue, the arguments without type
casting are typed by x64 (or x32 for 32bit arch) by default.
Note: all arguments set by old perf probe without types are
shown in decimal by default.
