NAK. There's no guarantee the dedicated dependency generators emit 
anything at all for scripts, for trivial reproducers this patch breaks 
dependency generation on these scripts:

#!/usr/bin/python
print "hello\n"

or

#!/usr/bin/perl
print "hello\n"

They might seem TOO trivial, but then think just how embarrassing it 
would be to entirely miss the dependencies of scripts SO trivial :) Also 
at least in case of Python, scripts where the only emitted dependency 
comes from the shebang line are the norm, not the exception.

Seems like a bad idea to me for a number of reasons, I'd suggest 
filtering at repo metadata instead of rpm level. Your distro though...
