Subject: CoreTap#install: fix clone target setting

When invoking `brew tap homebrew/core`, the input options will be like
`{ :clone_target => nil }`. This renders `Hash#merge` a dead operation.

It doesn't impact Homebrew itself, but could cause problem for
downstream projects Linxubrew/Tigerbrew when they adopt core/formula
separation.
