tool/generic_erb.rb: check ERB version

Browse source 
instead of Ruby's.

When older ERB is installed but Ruby is still 2.6.0, this may cause
error like:

```
Traceback (most recent call last):
    5: from ../src/tool/generic_erb.rb:36:in `<main>'
    4: from ../src/tool/generic_erb.rb:36:in `map'
    3: from ../src/tool/generic_erb.rb:43:in `block in <main>'
    2: from ../src/tool/generic_erb.rb:43:in `block (2 levels) in <main>'
    1: from /opt/local/lib/ruby/2.6.0/erb.rb:873:in `result'
/opt/local/lib/ruby/2.6.0/erb.rb:869:in `block in result': no implicit conversion of Hash into Integer (TypeError)
```

For safety, I changed this to check ERB's version. See also: r62529.
