    MockModuleBuilder: Fix thread safety problem with distgit-clone-wrapper
    
    Multiple build threads would try to write to the same distgit-clone-wrapper
    location, which could result in ETXTBSY when one thread tried to execute
    a script that another was writing to or vice-versa.
    
    Instead of using a wrapper script, use a sh -c invocation for distgit_get.
