verilog_parser: Fix Bison warning

As of Bison 2.6, name-prefix is deprecated. This fixes
frontends/verilog/verilog_parser.y:99.1-34: warning: deprecated directive, use ‘%define api.prefix {frontend_verilog_yy}’ [-Wdeprecated]
 %name-prefix "frontend_verilog_yy"

For details: https://www.gnu.org/software/bison/manual/html_node/Multiple-Parsers.html

Compile tested only.
