Use correct table name in GenerateDynCalls (#3560)

GenerateDynCalls was hardcoding the table name to use in the call_indirects in
the dyncall thunks. The hardcoded name was different from the default name for
imported tables, so the call_indirects referred to a nonexistent table when
dynamic linking was enabled. This PR instead uses the name of table 0 when
creating call_indirects for the dyncall thunks.
