Clean-up gdb.ada test names

Clean-up gdb.ada test names

This patch fixes all duplicate and tail parentheses test names.
These can really hinder automated test analysis such as used by
the buildbot.

Before:
$ cat testsuite/gdb.sum | egrep "^(PASS|FAIL|XPASS|XFAIL|KPASS|KFAIL)" \
  | sort | uniq -c | sort -n | grep -v " 1 "
      2 PASS: gdb.ada/attr_ref_and_charlit.exp: print s'last
      2 PASS: gdb.ada/bp_on_var.exp: set breakpoint pending off
      2 PASS: gdb.ada/complete.exp: complete p pck.inne
      2 PASS: gdb.ada/fun_overload_menu.exp: multiple matches for f (f (1, null))
      2 PASS: gdb.ada/type_coercion.exp: p q
      2 PASS: gdb.ada/unc_arr_ptr_in_var_rec.exp: print My_P_Object.Ptr when no longer null
      3 PASS: gdb.ada/fun_overload_menu.exp: 1

After:
<empty>

For parentheses, I've audited all occurrences of trailing parentheses.
Most offenders are of the form:

   gdb_test "p func (..)" $expected_result

I've either added a unique test name or simply removed the whitespace
between the function name and the argument list.
