staging: vme: clean up duplicate definitions of dependencies

The file staging/vme_user/Kconfig is only included by the top-level
staging/Kconfig if STAGING is enabled. So, there is no need to mention the
dependency on STAGING within the vme_user Kconfig file. Further, the config
VME_USER is already within the "if VME_BUS" block, so there is no need to
mention the dependency on VME_BUS.

Clean up these duplications of dependencies. No semantic change.
