Update show_asr_result.sh

[kamo-naoyuki]

Issue:

show_asr_result.sh expects the result in exp/*/*/score_*/result.txt. If the data set has more deep hierarchical directory structure e.g. data/foo/bar/train_set, it doesn't work properly.

Modify:

• Change the default value of maxdepth to 10
• Change the subsection name of the generated markdown file: ## $(basename ${expdir}) -> "## ${expdir}"
• Bug fix of printing ${expdir}/*/*/score_wer/scoring/*.filt.sys: no such file or directory
