[PATCH] vbox: Make host CPU cache init non-fatal

[Charlie Sharpsteen <source@xxxxxxxxxxxxxx>]

This commit updates the vbox driver to log a warning if the
virCapabilitiesInitCaches function fails instead of treating failure
as a fatal error. CPU cache initialization requires the sysfs filesystem
in order to complete successfully and thus fails on platforms such as macOS.

This commit is similar to ace6528ae19, which made the same change to the
VMware driver.
