[PATCH 0/1] MR10186: ntdll: Remove unnecessary strdup call

[Nikola Kuburović (＠kubni)]

Use the wineloader string directly because execv in preloader_exec
only reads it, so there should be no worries about
it getting modified.
Fix the memory leak that happens because duplicated wineloader
string memory isn't freed.

execv frees the entire address space, and if execv fails the process exits, so there's no leak to fix.
