extlibs: Use patch as fallback and trap errors

This will be helpful for Tizen and others OS.

If lib is bundled as "imported git patch"
then application of "duplicated ocf.patch as git patch",
is not needed anymore, and relies on scons.

To Tizen maintainers:
From now on let's maintain only one version in tree,
ealier versions of git patches can be reverted,
