[201811][warm-reboot] Remove warmboot file path that overrides the default path (#6201)

Browse Source 
This PR adds the changes in #6198 to 201811 branch to support warm-reboot image upgrade for kvm images.

The sai.profile file in kvm images overrides the warmboot file with path /var/cache/sai_warmboot.bin. Since the directory /var/cache is not mounted in syncd, it will be cleared in an image upgrade, the warm-reboot image upgrade will fail if the file is put in the directory.

Remove the path that overrides the default path. The warmboot file path will then be the default value /var/warmboot/sai-warmboot.bin. Since /var/warmboot/ is mounted by /host/warmboot/ in the host, it could survive an image upgrade.
