Allow _ characters in SQL prompts

* lisp/progmodes/sql.el (sql-product-alist): Allow _
characters in SQL prompts (bug#22596).

Fixes issue 22596, whereby "_" is now not considered a word constituent
character in sql-interactive-mode, so prompts like "foo_dev# " are not
correctly detected. Rather than piggy-back on the symbol table, we
explicitly match against alphanumeric chars or "_".
