Build: change the first parameter of TOOL_ADD_IMG to lowercase
In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.
Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.
make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist. We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.
