openocd: drop empty string suffix from format strings

Format strings are often split to allow using the conversion
specifiers macros from <inttypes.h>.
When the format string ends with one of such macros, there is no
need to add an empty string "" after the macro.

In current code we have 203 cases of empty string present, against
1159 cases of string ending with the macro.

Uniform the style across OpenOCD by removing the empty string.

Don't modify the files 'angie.c' and 'max32xxx.c' as they are
already changed by other independent commits.
