Disable automatic dependencies in zfs-test package

[behlendorf]

Description

All of the ZTS test scripts specify /bin/ksh as the interpreter.
Unfortunately, as of Fedora 27 only /usr/bin/ksh is provided by
the package manager. Rather than change all the scripts to
accommodate the latest Fedora disable automatic dependencies
for the zfs-test package. Functionally this will not cause
any problems since /bin is a symlink to /usr/bin.

Motivation and Context

Fix Fedora 27 automated testing.

How Has This Been Tested?

Locally.

@behlendorf This is technically a bug for Fedora ksh package. Did anyone ask the ksh maintainer to restore the /bin/ksh Provides?

[Conan-Kudo]

Actually, it looks like this has been fixed: https://bodhi.fedoraproject.org/updates/FEDORA-2017-2094282f35

[behlendorf]

@Conan-Kudo yes, this was discussed with the maintainer and addressed as you mentioned above. We may want to back this change out after the dust settles a little bit.
