    Fix build order of BUILD_VMOD_$NAME m4 macro
    
    When a VMOD adds a CFLAG with `libvmod_$1_la_CFLAGS` the object name is no
    longer `vmod_$name.lo` but `$library-vmod_name.lo` this changes the
    build order such that the VCC autogenerated files would not be
    guaranteed to compile first causing compilation issues.
