When the list of headers do not fit into the command line, xargs splits
it into several lists and then passes them to grep. If no headers from
a list match the grep pattern, grep exits with a non-zero code that causes
xargs to exit with a non-zero code, too.
* maint/ioctls_sym.sh: Use find's -exec instead of xargs;
Ignore it's exit code.
