dist is a strange dual-use target, as both a flag and a goal. make dist
<target> means build <target>, but copy any dist-for-goals files to
$DIST_DIR. make dist without a target means build droid with
dist-for-goals files. This requires special handling of MAKECMDGOALS to
detect the case where dist is the only goal, which breaks when ninja.mk
doesn't pass all the goals to kati. Instead, let ninja handle the
default goal. Pass dist to kati if it is specified in order to turn on
the dist-for-goal rules, but filter it out of the goals passed to
ninja. If there are any other goals, ninja will build them. If there
are no goals, ninja will fall back to the default goal, which is droid.

You can dist the same file for multiple goals in multiple calls to
dist-for-goals. The first call will establish the real copy rule, while
the rest call just establishes the goals' dependency on the dest file.
This enable uss to remove the bizarre $(if ..) enclosing the droid and
sdk dist while avoiding make's multiple rules warning.
