95fcoe: load 'libfcoe' module as a fallback
    
    The kernel may only enable 'libfcoe' module. Some modules like bnx2fc
    provides FCoE but only depend on 'libfcoe'. Loading 'fcoe' module may
    fail but the kernel do support FCoE.
    
    'libfcoe' will be installed as a dependency when installing block device
    drivers if it's required. So no need to install it in installkernel.
