[poky][PATCH] run-postinsts: do not remove postinsts directory.

["Anton Kachalov" <gmouse@google.com>]

From: "Anton D. Kachalov" <gmouse@google.com>

When running on the systems having read-only rootfs backed by overlayfs,
removing the whole directory lead to create a special char device file
on the upperdir to reflect directory's removal. Once it is required to
upgrade the whole read-only image that might contain new postinsts scripts,
it will be impossible to run such scripts with a "deletion mark" file
on the overlayfs -- the whole directory will be marked as deleted regardless
new files in it.
