targetinfo/touch: make it work with quiet ptxd_make

For ptxdist menuconfig kernel/barebox etc. 'make' is called without logging. As
a result PTXDIST_FD_STDOUT is not set. This causes bash sytax errors in
targetinfo/touch when PTXDIST_QUIET is defined.
Without logging 'quiet' doesn't work anyways, so just skip the special output
that uses PTXDIST_FD_STDOUT in this case.
