Add support for the C variable in the coccicheck script
This patch makes it possible to use the Coccinelle checker with the C variable of the build system. To check only newly edited code, the following command may be used: 'make C={1,2} CHECK="scripts/coccicheck"' This runs every semantic patch in scripts/coccinelle by default. The COCCI variable may additionally be used to only apply a single semantic patch.
