lib/oe/path: Deploy files can start only with a dot

There might be only hidden files deployed. In that case we don't need a
generic wildcard present in copy command, otherwise it fails with:

Exception: subprocess.CalledProcessError: Command 'cp -afl --preserve=xattr ./.??* ./* <BUILDDIR>/tmp/deploy/images/qemux86-64' returned non-zero exit status 1.

Subprocess output:
cp: cannot stat './*': No such file or directory
