macos does not have lazy unmount, so let's not use it
on linux either.
If the unmount fails, run "lsof" to find the open file.
Also fix the first bug we found this way.
To Go test logic waits for stderr and stdout to close, so
when we share it with a subprocess, it will wait for it to
exit as well.
We don't want the tests to hang when the unmount fails.
Seen on MacOS as reported at

The expected allocated sizes are verified for tmpfs and ext4.
btrfs gives different results, but that's not an error.
Also, simplify test_helpers.Du and several code paths.
Fixes#43.
This should make it work on OSX.
Also, split unmount into two functions. Depending on what you
want,
* UnmountErr returns the resulting error
* UnmountPanic panics if the error was not nil
...and add tests for checking that gocryptfs.diriv
does not get created.
The main "integration_tests" package has become quite
big and convoluted over time.
This small separate package should make writing tests
for "-plaintextnames" easier.
As seen in "fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir",
we need more of them.
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.
To make this work, test_helpers is also split into its own package.
