backends: ensure that test executables can be run when passed as arguments

If an executable is passed as an argument to a script in the build
directory that it resides in then it will not execute (on *nix) due to a
lack of ./. Ie, `foo` must be called as `./foo`. If it is called from a
different directory it will work. Ie `../foo` or `bar/foo`.

Fixes #5984
