[OpenWrt-Devel] [PATCH 1/2] scripts/metadata.pm: avoid adding dup names in provides list

[Yousong Zhou]

The need arises from building Open vSwitch kernel datapath modules, e.g.

 - kmod-openvswitch from Linux upstream
 - kmod-openvswitch-intree from openvswitch source code

where both provides virtual package "kmod-openvswitch" for userspace
packages to select and depend on
