InnoDB: Fix ut0dbg compilation errors on NetWare

innobase/dict/dict0boot.c:
  Remove dummy code to work around bug in the pgcc compiler.
innobase/include/ut0dbg.h:
  UT_DBG_PANIC: Avoid exit(), as lexyy.c re-#defines exit().
  Move the code to the function ut_dbg_panic() instead.
innobase/ut/ut0dbg.c:
  [__NETWARE__] Add function ut_dbg_panic()
