firmware/Makefile: remove -Wredundant-decls

Browse Source 
picolibc has redundant declarations of free and strdtold, which results
in lots of warnings with -Wredundant-decls. Adjust CFLAGS to remove
-Wredundant-decls to make the compiler log more readable.

  /usr/lib/picolibc/arm-none-eabi/include/stdlib.h:147:9: warning: redundant redeclaration of 'free' [-Wredundant-decls]
    147 | void    free (void *) __nothrow;
        |         ^~~~
  /usr/lib/picolibc/arm-none-eabi/include/stdlib.h:99:9: note: previous declaration of 'free' with type 'void(void *)'
     99 | void    free (void *) __nothrow;
