libalpm/package.c : fix requiredby with multiple providers.

Browse Source 
The code didn't match the following comment :
"A depends on B through n depends <=> A listed in B's requiredby n times"

It stopped at n=1 with a break.

I was surprised to see this case happens in real, that's how I noticed the
bug: wine depends on both freeglut and glut, while freeglut provides glut.

So when installing wine, the update_depends function listed wine twice in
freeglut's requiredby.  But the compute_requiredby function (used when
installing freeglut, and used by testdb) listed wine only once in
freeglut's requiredby.  That made testdb unhappy.
