Eliminate memtrack variability from the lost RAM calculation

Modify lost RAM calculation to use total mapped dmabuf and private GPU
allocations instead of memtrack HAL's reported Graphics and GL values.
All of memtrack HAL's reported Graphics should be accounted for as part
of mapped dmabufs. In order to not count it twice and not to depend on
memtrack HAL's reported value we exclude it from total PSS calculation
and replace it with mapped dmabufs.
All of memtrack HAL's reported GL should be accounted for as part
of private GPU allocations. In order to not count it twice and not to
depend on memtrack HAL's reported value we exclude it from total PSS
calculation and add GPU private allocations to total kernel memory
usage.
