cli: Replace printf_err with BT_CLI_LOGE_APPEND_CAUSE

The printf_err macro is currently used to report an error in the CLI.
However, we now have a proper error reporting framework.  This patches
makes the CLI use it.

All usages of printf_err are replaced with BT_CLI_LOGE_APPEND_CAUSE.

All usages of print_err_oom are replaced with a new macro that calls
BT_CLI_LOGE_APPEND_CAUSE("Out of memory.").

I haven't tested all the errors paths to make sure they worked well, but
here are some examples of the result:

    $ babeltrace2 convert --run-args --legault

    ERROR:    [Babeltrace CLI] (/home/smarchi/src/babeltrace/src/cli/babeltrace2.c:2874)
      Command-line error: retcode=1
    CAUSED BY [Babeltrace CLI] (/home/smarchi/src/babeltrace/src/cli/babeltrace2-cfg-cli-args.c:3621)
      While parsing command-line options, at option --legault: unknown option

    $ babeltrace2 convert --run-args -i salut
