add, update-index: fix --chmod argument help

Don't translate the argument specification for --chmod; "+x" and "-x" are the literal strings that the commands accept. Separate alternatives using a pipe character instead of a slash, for consistency. Use the flag PARSE_OPT_LITERAL_ARGHELP to prevent parseopt from adding a pair of angular brackets around the argument help string, as that would wrongly indicate that users need to replace the literal strings with some kind of value.
