Enable/disable pyzfs explicity in spec

[utopiabound]

Add --with/without pyzfs to rpm build

Explicitly enable or disable pyzfs during configure based on
what will be packaged. Configuration test should not make
packaging fail if python-cffi is installed.

Partially Addresses Issue #7882

Signed-off-by: Nathaniel Clark nathaniel.clark@misrule.us

Motivation and Context

Explicitly enable or disable pyzfs during configure based on what will be packaged. Configuration test should not make packaging fail if python-cffi is installed.

Description

If building pyzfs package, enable pyzfs in configured, and disable if not building pyzfs.

How Has This Been Tested?

Built locally on CentOS 7.4 with and without pyzfs.

I think a more comprehensive approach is already being proposed in #8096
