lib/oe/copy_buildsystem: fix merging sstate directories for eSDK
When we don't have uninative enabled there's more merging to be done in
the default configuration (SDK_EXT_TYPE = "full" which by default means
SDK_INCLUDE_TOOLCHAIN = "1") and there are likely files that already
exist in the sstate feed we're assembling, so we need to take care to
merge the directory contents rather than just moving the directories
over. Additionally we now only run this if uninative genuinely isn't
enabled (i.e. NATIVELSBSTRING is different to the fixed value of
"universal".)
In the process of fixing this I discovered an unusual behaviour in
os.rename() - when we're merging these feeds we're dealing with
hard-linked sstate artifacts, and whilst os.rename() is supposed to
silently overwrite an existing destination (permissions allowing), if
you have the source and destination as hardlinks to the same file then
the os.rename() call will just silently fail. As a result the code now
just checks if the destination exists and deletes the source if so
(since we know it will be the same file, we don't need to check in this
case.)
