ddb: use 'textdump dump' instead of 'call doadump'

Browse Source 
The change is for the example in textdump.4 and the default ddb.conf.

First of all, doadump now requires an argument and it won't do a
textdump if the argument is not 'true'.
And 'textdump dump' is more idiomatic anyway.

For what it's worth, ddb 'dump' command seems to always request a vmcore
dump even if a textdump was requested earlier, e.g., by 'textdump set'.
Finally, ddb 'call' command is not documented.
