bpftool: Set program type only if it differs from the desired one
After commit d6e6286a12e7 ("libbpf: disassociate section handler on explicit bpf_program__set_type() call"), bpf_program__set_type() will force cleanup the program's SEC() definition, this commit fixed the test helper but missed the bpftool, which leads to bpftool prog autoattach broken as follows: $ bpftool prog load spi-xfer-r1v1.o /sys/fs/bpf/test autoattach Program spi_xfer_r1v1 does not support autoattach, falling back to pinning This patch fix bpftool to set program type only if it differs.
