patches/act: Fix crash with no accounts

This ACT patch changes a function with counts the number of accounts of
the system to always report 1 account. If there are no accounts, such as
on a system format or on a fresh Citra instance, this would make the
sysmodule try to read from non-existent data.

We replace the patch to allow the sysmodule to enter the counting loop,
but only once. After finishing the loop, we jump out of it to the end
and return the count.
