tests: check backing filesystem can handle large file 

The new resize tests create 2TB test files, but tmpfs in kernels
before 3.1 have a max file size of 256GB.  Ext3 may also have
a size limit for smaller blocksize filesystems.

Fix the resize_test script to verify that $TMPFILE can be resized
to the final test size, and if that fails try creating the file on
the local filesystem instead of in $TMPDIR.  If that cannot hold
the large filesystem, skip the test.
