[PATCH 3/5] coccinelle: exclude sha1dc source files from static analysis

sha1dc is an external library, that we carry in-tree for convenience or grab as a submodule, so there is no use in applying our semantic patches to its source files.

Therefore, exclude sha1dc's source files from Coccinelle's static analysis.

This change also makes the static analysis somewhat faster: presumably because of the heavy use of repetitive macro declarations, applying the semantic patches 'array.cocci' and 'swap.cocci' to 'sha1dc/sha1.c' takes over half a minute each on my machine, which amounts to about a third of the runtime of applying these two semantic patches to the whole git source tree.
