[PATCH 2/4] Coccinelle: Cleanup the setting of the FLAGS and OPTIONS variables

[Nicolas Palix <nicolas.palix@imag.fr>]

The FLAGS variable is factorized independently of the ONLINE mode.
The OPTIONS variable is now based on LINUXINCLUDE and explicit
includes are thus removed.

The format of the -I option differs between gcc and spatch.
The COCCIINCLUDE is used to adapt the format. This rewritting
needs bash.
