[libvirt] [PATCHv2] selinux: Fix incorrect file label generation.



This is an ad-hoc fix for the file label generation. It uses the base context
role to determine whether to use the libvirt process context role. If this
is object_r we don't touch it.
It might be better to add a new flag to virSecuritySELinuxGenNewContext that
specifies the context type (process or file) in the future.

V2 Change:
Use STRNEQ instead of strlen.
