Linuxmodule proclikefs: Use a static array of proclikefses.

Rather than dynamically allocating proclikefses. Kevin Herbert
provided a similar patch, since he compiles at Meraki with lock
checking, and (apparently) proclikefs's dynamic allocation defeated
lock checking. Since only Click uses proclikefs, why not simplify it.
