makepkg: don't let the strip routine mess up file attributes
It updates the stripped/objcopied file by creating a temp file, chown/chmodding it, and replacing the original file. But upstream binutils has CVE-worthy issues with this if running strip as root, and some recent versions of strip don't play nicely with fakeroot. Also, this has always destroyed xattrs. :/ Sidestep the issue by telling strip/objcopy to write to a temporary file, and manually dump the contents of that back into the original binary. Since the original binary is intact, albeit with different contents, it retains its correct attributes in fakeroot.
