build: fixed a problem with installing scripts in the build tree

the SAMBA_SCRIPT() function was not always triggering correctly. The
base problem was that we were using a target outside the build
tree. This implements a simpler solution where we just create the
links directly in SAMBA_SCRIPT() rather than creating a waf task
