[PATCH util] Bumped -I flag limit in makedepend from 64 to 512.

[David Boyce]

Clearly a limit of 64 -I flags is too low (we hit it); it might be
a good style recommendation but shouldn't be a hard limit.
512 is a fairly random replacement value.

For our own purposes we could get by with a doubling to 128, but there
doesn't seem to be a substantial memory footprint issue here so the
maximum could go much higher. I picked 512 more or less at random.
