[patch] getting /pari out of includedir

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello PARI-dev,

This patch change the semantic of includedir to not include the pari suffix.
Instead /pari is automatically added my make install.

This make much sense since using an includedir that does not end by
/pari would break the API, since #include <pari/pari.h> would not work.

In particular the patch change extgcd.c to say #include <pari/pari.h>
instead of #include <pari.h> which is better for an example.

Cheers,
Bill
