commit c468820ba9 "scripts/build: cleanup"
started to silently remove *.o files from the installation without
giving an explanation why this should be needed.
Drop that as it prevents packages from including *.o files in the
image, which eg is needed to include IR BPF decoders in LibreELEC.
Packages which install *.o files that should not end up in the image
should manually remove these in post_makeinstall_target.

cp (and potentially mkdir -p) are not atomic, and we have seen situations where two packages
concurrently copying the same file (eg. the udev rule for xf86-video-nvidia and
xf86-video-nvidia-legacy) will succeed for one package but the other package fails with
a "file exists" error (as the file didn't exist when it checked, but does exist when it
actually copies the file). Not even cp -f will avoid this issue.
There are several workarounds, but the most practical (and general) solution is to ensure
sequential updates of the image and shared sysroot directories.
