Subject: [PATCH] refind: fix runtime errors

In newer versions, instead of using $PWD to locate its ressource files,
Refind now refers to the dir containing $0.
This causes runtime errors due to missing ressources.

In lieu a wrapper binary, we now simply patch the variable 'RefindDir'
which stores the path to the ressource dir.
