Linux memory information ctypes might be too small

When printing out base addresses of a process's regions from this struct, I noticed they were truncated to 32 bits after comparing to the smaps under /proc.

The c_int types can be 32 bit instead of 64 bit, even on a 64 bit machine, and should probably instead be c_uint64.
Alternatively, don't use a ctypes structure here because it does not seem to be used by any C functions anyway, and instead use a regular class or namedtuple.

Since the wrapping dictionary contains the base address as the unaltered python int, that is a workaround for reading that specific field.
