fix a logic error from 2018: be silent if any of -S, -n, -q are mentioned.

fix a logic error from 2018: be silent if any of -S, -n, -q are mentioned.

The actual bug reverted in 1.128 was from "make print-plist-libs"
which would invoke pkg_create -n -Q  and filter out the libs: but
in that case, pkg_create would not be silent, thus yielding
    reading plist|-/usr/local/lib/libpython3.9.so.0.0
to filter, which obviously wouldn't work.

So, turn on silent mode for -Q as well.
