Remove range_sha1 check on block partition(s)

* some installer-scripts are using "if range_sha1("/dev/block/platform/msm_sdcc.1/by-name/system",...) == "<sha1_hash>" then ..." which obviously breaks multirom rom flashing to secondary since this condition will always be false
* workaround -> remove the check and let it always be true
