[OE-core] [PATCH] license.bbclass: run chown only under pseudo

[Markus Lehtonen]

The copy_license_files() function in license.bbclass is called in two
different contexts. First, it is run as part of the do_populate_lic
task. In addition, it is called from do_package task when
LICENSE_CREATE_PACKAGE is enabled. The function has code that changes
the owner of license files to root which is meant only to happend in the
latter case - i.e. under do_package which is run under pseudo.
Previously, the code was blindly always running chown and just ignored
errors that happened when running from do_populate_lic. This patch
changes it to be more intelligent, only doing chown when running under
pseudo.
