Do not ignore conditionals of the form "%if ... %{name} ..."

Pass --keep-name-conditionals option to the helpers/spec_query script
in order to take conditionals of the form "%if ... %{name} ..." into
account.
This is a fix for commit 0cb8321 ("Don't use rpmbuild to extract
sources, patches etc. from a spec").

Fixes: #55 ("source validator fails on openSUSE:Factory/coreutils")
