CTF doesn't have support for multiple array dimensions, so it flattens
the arrays.
This caused a large number of false positives in ctfdwdiff, so introduce
this conf_fprintf option, use it in pahole and ctfdwdiff.

For a file with just DWARF info:
$ pahole -F ctf build/pahole
$
But if we ask that it also try dwarf:
$ pahole -F ctf,dwarf build/pahole | head -2
struct _IO_FILE {
int _flags; /* 0 4 */
$
Useful when testing the new CTF support in these tools, as we'll be able to,
from the DWARF info in objects, generate the CTF equivalent and add to the same
object, then run pahole -A -F ctf, pahole -A -F dwarf and compare the outputs.
