ios: Properly handle overflows in scoped_vm_read.

Passing -1 (or size_t max) to ScopedVMRead would succeed, because the
amount of memory to be read would overflow vm_address_t/vm_size_t and
turn into something reasonable. ScopedVMRead would return true having
only read a miniscule subset of the requested data length.
