meta-openembedded/all: adapt to UNPACKDIR changes

Please see
https://git.yoctoproject.org/poky/commit/?id=4dd321f8b83afecd962393101b2a6861275b5265
for what changes are needed, and sed commands that can be used to make them en masse.

I've verified that bitbake -c patch world works with these, but did not run a world
build; the majority of recipes shouldn't need further fixups, but if there are
some that still fall out, they can be fixed in followups.
