[OE-core] [PATCH 1/2] adt-installer: check if sudo is needed when installing target sysroot

[Laurentiu Palcu]

Currently, if SDK is installed in a directory that needs sudo
preivileges, the target sysroot is also installed with sudo, even though
the location is in users's home directory.

This patch reuses the ownership checking code and uses it to check if
sudo is needed for target sysroot too.
