fscache: Move fscache_cookies_seq_ops specific code under CONFIG_PROC_FS
fscache_cookies_seq_ops is only used in proc.c that is compiled under
enabled CONFIG_PROC_FS, so move related code under this config. The
same case exsits in internal.h.
Also, make fscache_lru_cookie_timeout static due to no user outside
of cookie.c.
