A cleanup for MDEV-30932 UBSAN: negation of -X cannot be represented in type ..

"mtr --view-protocol func_math" failed because of a too long
column names imlicitly generated for the underlying expressions.

With --view-protocol they were replaced to "Name_exp_1".

Adding column aliases for these expressions.
