deps: cherry-pick 1383d00 from v8 upstream

Original commit message:

    tools: fix tickprocessor Cpp symbols on mac

    Despite man page documentation:

        -f Display the symbol table of a dynamic library flat (as one
           file not separate modules).

    `nm` on mac treats `-f` as a shorthand for `-format`. The `-f` argument
    does not seem to be required, so just remove it completely.

    (For `-format` documentation - see `nm --help` on mac).
