    libgimpbase: display thread id of the calling thread as hexadecimal...
    
    ... on macOS.
    The debugger running on macOS is usually lldb and (from the reports we
    get) it looks like lldb displays the tid as hexadecimal on macOS
    (whereas lldb displays decimal tid on Linux! I know, it's confusing, yet
    consistent with crash report experience!). So let's just do the same,
    making it easy to quickly copy-search in order to look up the crashing
    thread (without having to convert from decimal to hexa).
    This is a bit of an approximation as I imagine we could have gdb on
    macOS or whatever edge case. Let's say it's good for the common case and
    still not an error otherwise (just a base conversion away).
