It is possible for the runtime to receive an interrupt while trying to
access VRAM data using /proc/self/mem. In such case, pread(2) would
return -1 and set errno to -EINTR. This is not an error case, the
pread(2) call just need to be restarted, however current implementation
would tread it as an error.
This patch changes the the implementation to correctly retry on EINTR.
While at it, this patch also handles cases where pread(2) reads less
data than originally requested.
