build: Rename cloned repositories and remove cuse

VSPERF expects folders to be named a certain way, but this may not be
the case if another repository is specified via the package-list.mk
file. One example of this is the DPDK stable repo which gets cloned to
the "dpdk-stable" directory unless otherwise specified. Thus Makefiles
were updated to enforce expected folder names.

Unused configuration related to vHostCuse support was removed.
