Make sh_binary create temp files within the buck-out/gen instead of /tmp
Make sh_binary create temp files within the buck-out/gen instead of /tmp

Summary:
sh_binary execution originally would create folders outside `buck-out`
due to calling `mktemp -d -t ...`, which creates folders in `/tmp`.

This removes `-t` flag, which creates the folder in the "current" dir, which would
be the dir of the shell script in `buck-out/gen`
