Patch by Jean Wolter to fix a bug where a script wouldnt be executed

unless it had #!/bin/sh in the first line

"It correctly locates the script, tries to execute it via execve which
fails. After that it tries to hand it over to /bin/sh which fails too,
since ash

    - neither provides the absolute pathname to /bin/sh
    - nor tries to lookup the script via PATH if called as "sh script"
"
