Busybox shouldn't need to link with libxcrypt if USE_BB_CRYPT is
enabled (which it is in OE's default Busybox defconfig).

There's a long standing bug in Busybox whereby crypt.h gets included
unconditionally (instead of being guarded by #if ENABLE_USE_BB_CRYPT
etc) so the Busybox recipe still needs to depend on virtual/crypt but
it's only a compile time dependency.
