Fix commands for openocd 0.10.0

Fix bug introduced by 5704a06
Double/triple {} surrounding filenames are not needed on unix but are on Win.

openocd 0.10.0 tcl interpreter (jimtcl) doesn't resolve curly braces recursively, while old did.

By surrounding with just one curly brace 0.10.0 is happy

Fixes #426 and #422
