Subject: [PATCH] automated: linux: allow disabling custom variable in
 ota-update

This patch allows to set empty u-boot custom variable name. This will
prevent the test script from attempting to set the variable during the
test. It is important for boards that use RPMB with only a list of
allowed variables.
