[kexec-tools] omit dash module

[Dave Young]

commit b14b69224296442aa7574c6e58ca553ac6626211

    omit dash module
    
    dash is be default omited in f17, but we use -o in command line so our omit
    modules list will overwrite the system configs, so dash will be installed to
    initramfs.
    
    Here avoid install dash by adding it to the '-o' list
    Also remove dash dependency from rpm spec
