bpftool: Using the right format specifiers
Fixed some formatting specifiers errors, such as using %d for int and %u
for unsigned int, as well as other byte-length types.
Perform type cast using the type derived from the data type itself, for
example, if it's originally an int, it will be cast to unsigned int if
forced to unsigned.
