[PATCH 1/1] modules: load modules from /var/run/qemu/<version> directory firstly

[Siddhi Katage <siddhi.katage@oracle.com>]

From: Siddhi Katage <siddhi.katage@oracle.com>

An old running QEMU will try to load modules with new build-id first,this
will fail as expected ,then QEMU will fallback to load the old modules that
matches its build-id from /var/run/qemu/<version> directory .
Make /var/run/qemu/<version> directory as first search path to load modules.

Fixes: bd83c861c0 ("modules: load modules from versioned /var/run dir")
