Replace clear_hook_in_cleanup with scoped_restore_hook_in
This removes clear_hook_in_cleanup in favor of a scoped_restore-like
class. scoped_restore itself can't be used because hook_in is a
bitfield.
ChangeLog
2017-09-11 Tom Tromey <tom@tromey.com>
* cli/cli-script.c (class scoped_restore_hook_in): New.
(clear_hook_in_cleanup): Remove.
(execute_cmd_pre_hook, execute_cmd_post_hook): Use
scoped_restore_hook_in.
