Fix AT_EXECPATH for direct exec mode.

Authored by kib on Dec 20 2019, 10:12 PM.



The somewhat problematic case is when the executable path is relative and either $PATH use is not enabled or it contains '/' so $PATH search is not performed. In this case AT_EXECPATH is relative, I might fix this later.
