We don't have perfect control of file allocation for these tests; in some cases we may fail to adequately fragment a file prior to defragmentation testing, and today that will fail the test. Attack this on 2 fronts: 1) Explicitly allow fewer extents on one of the input files in generic/018 where the allocator has discretion. 2) _notrun rather than _fail if we don't create enough extents; this is a defrag test, not an allocator/fragmentation test, so just skip the test if we can't create an acceptable file for defrag testing.
