NIFI-995: TestGetFile failed in case of NTFS partition in Linux
I cloned the NiFi source code to local directory on a NTFS partition in
Linux, and was surprised, when one of the standard test case failed on my box.
The problem was with the last step of `TestGetFile.testAttributes()`, which
checks, whether the file permission modification is working.
The original implementation used `Files.setPosixFilePermissions()` method
to set the file permission, and if no exception was raised
(`verifyPermissions`), it made this file permission check.
If you have a NTFS partition mounted in Linux, you are unable to change the
permissions of your files, which is controlled globally with the `fmask` and
`dmask` mount options. It means, that you are able to run `chmod` commands
without any error, but it does not have any effect.
From Java perspective, the `Files.setPosixFilePermissions()` was successful
(no exception), but the file's permissions were not changed, and the last check
failed.
An extra check is needed and set `verifyPermissions` to true, only if the
`Files.setPosixFilePermissions()` changed the permissions of `targetPath`.

NIFI-995: Fix for TestGetFile tests (only for NTFS)
TestGetFile.testAttributes() failed in case of a NTFS partition in Linux,
because Files.setPosixFilePermissions() did not have any effect on the files.
