vdi: don't override libuuid symbols
It's poor symbol hygiene to provide a global symbols that collide with a
common library like libuuid. If QEMU links against a shared library
that depends on uuid_generate() it can end up calling our stub version
of the function.
This exact scenario happened with GlusterFS libgfapi.so, which depends
on libglusterfs.so's uuid_generate().
Scope the uuid stubs for vdi.c only and avoid affecting other shared
objects.
