opkg-utils: backport a patch to fix a sstate timestamp issue

When using sstate, two parallel builds can produce two packages
with the same mtime but different checksums. When later one of
those two builds fetches the others ipk, the package index does
not get udpated properly (since mtime matches). This ends up with
messages such as:
  Downloading file:/../tmp/work/../image/...ipk.
  Removing corrupt package file /../sysroot/../var/cache/opkg/volatile/...ipk

However, in that case, ctime is different. Use ctime instead of
mtime to prevent failures like this.
