kvm-unit-tests: add gcc version dependencies

On x86 (both i386 and x86_64), the kvm-unit-tests code uses
__builtin_reachable, which appeared in gcc 4.5. This commit adds the
relevant dependencies to kvm-unit-tests:

 - on i386, we need gcc 4.5 as the target compiler

 - on x86-64, we need gcc 4.5 as the host compiler, because we use the
   host compiler to build kvm-unit-tests for this architecture

Fixes:

suggests, it's purpose is to provide unit tests for KVM. The
