[OE-core] [PATCH 2/4] classes/package_tar: fix conflicts with package_deb / package_ipk

[Paul Eggleton]

Avoid tar noticing that the directory is changing when
do_package_write_deb or do_package_write_ipk are running at the same
time as do_package_write_tar (because DEBIAN and CONTROL are being added
and removed while tar is running so the directory changes).

Fixes [YOCTO #5652]
