Restore default "yes" behavior for lint patch
Restore default "yes" behavior for lint patch

Summary:
Fixes T9029

See T9029 for more details, but basically at some point phutil_console_confirm
(which takes a `$default_no` parameter) was refactored to `$console->confirm()`
which takes a `$default` parameter with semantics negated..

Test Plan:
Run `arc lint` on a repository where patch is suggested. Default
option should be "[Y/n]" to accept the patch.
