curl-wolfssl.m4: without custom include path, assume /usr/include

... so that we can point out the root of the OpenSSL emulation headers.
Previously this used the '$includedir' variable which is wrong since
that defaults to the dir where the current configure invoke will install
the built libcurl headers: /usr/local by default.

Fixes #7085
Reported-by: Joel Jakobsson
Closes #7087
