Andreas Kling 890c647e0f Kernel: Fix off-by-one in Memory::is_user_range() check ...

This function was checking 1 byte after the provided range, which caused
it to reject valid userspace ranges that happened to end exactly at the
top of the user address space.

This fixes a long-standing issue with mysterious Optional errors in
Coredump::write_regions(). (It happened when trying to add a memory
region at the very top of the address space to a coredump.)
