[PATCH 2/2][autotest-client-tests] UBUNTU: SAUCE: ubuntu_performance_fio: Change value of FIO global file_size_mb

[Ian May]

The new FIO tests use multiple file sizes, ubuntu_performance_fio.py does a check
of available RAM before starting the tests.  By initializing to the largest size used,
the check will still be valid.

Instead of inserting the global file size into the test file, changed to extracting the
file size out of the test file for display output.
