ccanlint: check for #ifdef

Old habits die hard; it's better to use #if <FEATURE> than #ifdef <FEATURE>;
they're similar, because undefined identifiers evaluate to zero, but with
GCC's -Wundef flag you can detect mis-spelled or missing features with
#if.

autoconf-style config.h leave unset features undefined, so this works for
those config.h too.
