Generalize hmp_split_at_comma() to take any delimiter string, rename

Simplify the exec migration code by using list utility functions.
As a side effect, this also fixes a minor memory leak. On function return,
"g_auto(GStrv) argv" frees argv and each element, which is wrong, because
the function does not own the individual elements. To compensate, the code
