unpack: prevent circular unpacking between two packages

Browse Source 
In case two packages has dependency on each other unpacking fails because unpack script goes to loop and eats all the computer resources. With this change unpack fails on third pass.
Probably this functionality could be done better but atm I don't have better idea.

unpack recursive limit hit [package1, package2]
