Execution bit detection fixes for VFAT on Linux

On Linux VFAT execution mode can be modified, but changes don't
persist a filesy stem remount. The current test can be trickled by
this. We can help with the det ection of VFAT checking whether new
files get created with the execution bits on
 (as usually these partitions are mounted with the exec option, for
convenience)

    Otherwise, each element is a 2-tuple:
