[PATCH] Fixed concurrency problem for ZIP packed recipes.

[Ihar Hrachyshka <ihar.hrachyshka@gmail.com>]

The problem occured when unzip-native is not yet staged, and ZIP
archive unpacking already started resulting in failed do_unpack task.
Added NEED_UNZIP_FOR_UNPACK variable to use in recipes which do_unpack
with unzip utility but doesn't have '.zip' in SRC_URI (f.e. .EXE
windows self-extraction binaries).
