Remove incorrect output with download only and IgnorePkg
When only downloading a package that is in IgnorePkg, pacman
incorrectly asks about installing.
e.g. with <pkg> in IgnorePkg in pacman.conf:
> pacman -Sddw <pkg>
:: <pkg> is in IgnorePkg/IgnoreGroup. Install anyway? [Y/n]
This output is now silenced when downloading only.

This moves the hiding of the output to the pacman callback rather than doing it
in the libalpmm backend as previously submitted. Note this is the same as how
the similar output issue with PM_TRANS_CONV_LOCAL_NEWER is handled.
