The macro expansion of an --eval need not return anything (eg, it could be a
lua script only run for its side effects). That --eval then prints an empty
line. A silly example:
`$ rpm --eval '%{lua: a = 1}' --eval '%{lua: print( "Hi!"
)}' --eval '%{lua: b = 2}'
Hi!
`
This trivial commit skips printing if the macro expansion is an empty string.
Tested lightly on rpm-4.20.1 (Fedora 42) and forward-ported to master.
