[ovs-dev] [RPMs v2 4/4] xenserver: Don't create XAPI cache at install.

[Justin Pettit]

From: Bob Ball <bob.ball at citrix.com>

There are two mechanisms of installing a supplemental pack – one is
after installation (using the xe-install-supplemental-pack command) and
one is during installation by either creating a new install ISO with the
supplemental pack bundled or creating an HTTP directory which serves the
install files and the new supplemental pack contents.

The RPM should support both methods, but currently attempts to backup
data that doesn't exist yet.  With this commit, the XAPI cache is not
created at install.
