The gem_render_linear_blits test tends to get oom killed
on low memory (< 4GB) Android systems. This is because the
test tries to allocate (sysinfo.totalram * 9 / 10) in
buffer objects and the remaining 10% of memory is not
always enough for the Android system.
After a discussion with Chris Wilson I have split this
test into a "basic" and an "apperture-thrash" subtest,
in the same way as gem_linear_blits. The basic test
uses just two buffer objects and the apperture-thrash
test is skipped if there is insuffiecient memory.

v2: Following comment from Chris Wilson:
    a) Remove the command line option for count.
    b) Add a third subtest to ensure swap is tested

v3: Replace some leading spaces with tabs

Please use the igt_main block instead of open-coding it. Same for your
other patch.

Spaces instead of tabs for indent.
