contrib/coccinelle: pass include paths to spatch(1)

In the previous commit a new coccinelle rule is added. But neiter
`make coccicheck` nor `meson compile coccicheck` did detect a case in
builtin/last-modified.c.

This case involves the field `scratch` in `struct last_modified`. This
field is of type `struct bitmap` and that struct has a member
`eword_t *words`. Both are defined in `ewah/ewok.h`. Now, while
builtin/last-modified.c does include that header (with the subdir in the
#include directive), it seems coccinelle does not process it. So it's
unaware of the type of `words` in the bitmap, and it doesn't recognize
the rule from previous commit that uses:

    type T;
    T *ptr;

Fix coccicheck by passing all possible include paths inside the Git
project so spatch(1) can find the headers and can determine the types.
