Remove stray line break when running root -q with input files

ROOT first prints a newline before going over the inputs to separate
printouts from the initial "root [0]" prompt. But if root is run with
"-q", there is no prompt and we don't need the newline.

Removing this spurious newline completely avoids all output when
building ROOT, where the newline used to happen when running
`hsimple.C`.

This is commit is similar to 8e8b6bb, which removed another
stray linebreak in the opposite case of running `root` with no input
files.
