[PATCH 4/7] generic/exportfs: store and load file handles from file

[Amir Goldstein <amir73il@gmail.com>]

For the test cases of renaming test directory and moving files
to new test directory, encoding the file handles is done after
files/dir have been renamed, so the test does not exercise decoding
file hanldes that were exported before the rename.

For those test cases, store the test set file handles to a temp
file, then move the files/dir, then try to open test set by stored
file handles.
