[PAHOLE]: Implement --decl_exclude 

pahole -D /pub/scm/linux/kernel/git/acme/net-2.6.20/include/net/ \
	  ../OUTPUT/qemu/net-2.6.20/net/ipv4/tcp.o

Will exclude all the classes that were defined in files in the
/pub/scm/linux/kernel/git/acme/net-2.6.20/include/net/ directory, note that its
a prefix, not a directory, so one could as well pass
/pub/scm/linux/kernel/git/acme/net-2.6.20/include/net/tcp_ to exclude just the
files in the include/net directory and that start with 'tcp_'.

Now I think I implemented what Bernard wanted, and that is useful for me
as well, of course :-)
