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.
