libbpf: Keep format strings of bpf_printk() in .rodata.str

bpf_printk(), BPF_SNPRINTF(), BPF_SEQ_PRINTF() and bpf_stream_printk()
copy the format into a static const array, which the compiler puts into
.rodata. When global data of the object is in arena .rodata is there
too and the helper doesn't take the format:

  R1 type=scalar expected=fp, pkt, pkt_meta, map_key, map_value, mem,
  ringbuf_mem, buf, trusted_ptr_, ctx

String literals are in .rodata.str1.1, which libbpf keeps in a read-only
map. No compiler flag moves a named array there. Put the arrays into
.rodata.str with a section attribute.

An object that uses the macros gets one more map, .rodata.str.
