Revert "libstore: using throwing finally in withFramedSink"

Browse source 
This reverts commit 491caad6f62c21ffbcdebe662e63ec0f72e6f3a2.

this is not actually legal for nix! throwing exceptions in destructors
is fine, but the way nix is set up we'll end up throwing the exception
we received from the remote *twice* in some cases, and such cases will
cause an immediate terminate without active exception.
