[PATCH nft] scanner: fix search_in_include_path test

[Anatole Denis <anatole@rezel.net>]

clang emits a warning in this function as we're using a boolean as the third
argument to strncmp. Indeed, this function only checks the first byte of the
path as is, so files beginning with . will be incorrectly included from the
current working directory instead of the include directory.
