[OE-core] [PATCH] sdk.py / OpkgSdk: remove_packaging_data() after install

[Haris Okanovic]

Run remove_packaging_data() on both host and target sysroots to wipe
opkg state after install, similar to what RpmSdk does.

Use case:

Opkg may download local package indexes (I.e. file:// URLs) by
sym-linking them into /var/lib/opkg/lists/ instead of copying [1].
This leaves behind broken symlinks under the lists directory when
using opkg to build SDK sysroots.

The -h option may be set via SDKTAROPTS in some configurations to create
symlink-less SDK archives for Windows file systems. Sysroots containing
broken symlinks will fail to archive under this configuration.

Testing:

Verified /var/lib/opkg/ is empty after running populate_sdk() in a Fido
based distribution.
