automate @VERSION@ in virt-manager.spec

This update renames virt-manager.spec to be
virt-manager.spec.in and changes the version-id to
@VERSION@ ... setup.py is modified to copy the
virt-manager-spec.in file to virt-manager.spec and
replace @VERSION@ with the current/actual version id.

.gitignore is updated to ignore virt-manager.spec
.
