[base-files] shell-scripting: fix wrong usage of '==' operator normally the '==' is used for invoking a regex parser and is a bashism. all of the fixes just want to compare a string. the used busybox-ash will silently "ignore" this mistake, but make it portable/clean at least. this patch does not change the behavior/logic of the scripts.
