[OE-core] [PATCH 1/7] package.bbclass: Create symlinks for packages with different packaged name

[Paul Eggleton]

From: Andrei Gherzan <andrei at gherzan.ro>

While generating license.manifest package information is searched in:
filename=`ls ${TMPDIR}/pkgdata/*/runtime/${pkg}| head -1`
This is ok as long as package name is the same as the package name
after packaging.
For example dbus is packaged as dbus-1. So, searching
ls ${TMPDIR}/pkgdata/*/runtime/dbus-1 will fail because there is no file
with this package name.

Create a symlink to the pkgdata file in a runtime-reverse directory so
that these reverse lookups are possible.

Fixes [YOCTO #2638].
