libalpm/remove.c : avoid duplicated packages in removal list.

Suppose a package foo depends on foo1, foo2, ..., foon.
Doing pacman -Rc foo1 foo2 ... foon added foo n times to the removal list,
because what checkdeps return is something like :
foo1 is requiredby foo
foo2 is requiredby foo
...
foon is requiredby foo
