Errata for SuperTest Aelbert Cuyp 5.0

• [5.0.45] The following test file had a typo. The impacted test file has been corrected.
  Cxx11/7/6/4/t_0002.gen
• [5.0.44] The following test files were deemed erroneous. The impacted test files have been corrected.
  Cxx11/22/4/2/1/1/t_throw.C has an incorrect grouping() check removed.
  Cxx17/10/6/6/t_0007.C was found to have invalid attribute specifier syntax and is thus removed.
  Cxx11/30/5/1/t_wait_until_negative.C and Cxx11/30/6/6/t_wait_zero.C were susceptible to timing out due to faulty behavior; they were subsequently fixed.
  Cxx14/7/6/5/xdfriendclassdecl100arg.C and Cxx14/7/6/5/xdfriendfuncdecl100arg.C had an ambiguous diagnostic line, both tests are now fixed.
  Cxx14/5/1/2/xgl3array1b.C and Cxx14/5/1/2/xgl3array2b.C tested a construct that was forbidden until C++23; they’re both fixed now.
